One Friday night, the McFly family had been invited over to a party and dance by Milton and Susan Baines. Marty and Calvin were both excited about going, even if Jennifer won't be there. Milton and Susan had a son named Brent, who was the same age as Marty and Calvin - and Brent had always been their favourite cousin. As soon as the family had arrived at the home, Brent ran out to greet Marty and Calvin.

'How are my favourite cousins doing?' asked Brent, as he hugged Marty.

'I'm doing very well, thank you,' replied Marty. 'How about you?'

'I have a girlfriend, now,' Brent said, happily, as he hugged Calvin. 'Her name is Molly Swick. She is such a sweetheart - and she adores heavy metal. I don't know too many girls who love heavy metal.'

'Jennifer listens to heavy metal,' Marty said, smiling.

'Jennifer Parker, you mean?' Brent asked, smiling. 'Oh, yeah, I remember her. You two make such a gorgeous couple. I'm not surprised that you two are still together.'

'Well, Jennifer and I are destined to marry someday,' Marty said, with a smile.

'So what about you, Calvin?' Brent asked. 'Do you have a girlfriend.'

'Uh, no, not really,' replied Calvin. 'I have a lot of female friends, but I'm not in love with anyone. I'm not too worried about it. The right girl will come along, eventually. I just have to be patient.'

'Oh, yes,' Brent said, smiling, 'you've always had your priorities. Molly and I have only been dating for two months, and she is the love of my life. However, I didn't fret over not having a girlfriend before Molly came along.'

'So where did meet Molly?' asked Marty.

'I met her at the roller rink,' replied Brent. 'She goes to the high school the next town over. I wish we went to the same high school, though.'

'Yeah, I don't really blame you, Brent,' Marty said, smiling.

'So, would you boys like a grasshopper?' asked Brent.

'Uh, you mean one of those alcoholic mint malt drinks?' asked Marty.

'Yeah, of course, silly!' Brent said, laughing. 'You didn't think I meant real grasshoppers, did you?'

'Uh, no, not really,' stammered Marty.

'I'll have a grasshopper,' Calvin said, eagerly. 'I bet they taste delicious.'

'Oh, you bet,' replied Brent, smiling. 'How about you, Marty?'

'Uh, no, thank you,' replied Marty.

'No?' Brent asked, astonished. 'Why not? You don't know what you're missing.'

'I just don't like to drink anything with alcohol in it,' replied Marty.

'What's the matter, Marty?' Brent asked. 'Chicken?'

'I'm not a chicken!' Marty retorted. 'I just don't like alcohol.'

'Well, okay, Marty,' Brent said, sighing. 'You don't know what you're missing, though.'

Marty just rolled his eyes. Marty had wanted nothing to do with alcohol, after seeing how alcohol had negatively affected his mother in the old timeline. He was a little surprised that Calvin had taken on Brent's offer of a grasshopper. Calvin was normally the sensible twin who tried to keep Marty from being too impulsive.

oooooooooo

About two hours later, Marty and Calvin joined each other on the dance floor, as music was playing. Marty was content with drinking fruit punch, while Calvin was drinking another thing of grasshopper.

'Are you sure you don't want at least a sip, Marty?' asked Calvin.

'Yes, Calvin, I'm sure,' replied Marty. 'I saw how alcohol can ruin my mother. So I just don't like alcohol.

'But this tastes good,' argued Calvin, 'much better than the shamrock shakes they serve at McDonald's in March.'

'Uh, Calvin, you might want to make this your last drink,' Marty said, gently. 'I don't want you to pass out.'

'I can take care of myself, Marty,' snapped Calvin. 'I don't need you lecturing me about how alcohol is bad for you. I'll be fine.' Then Calvin left in a huff.

Marty had sighed. He could hardly believe the arguement they just had. Usually, Calvin was the one lecturing Marty on something or another - and Marty was the one to insist that he didn't need to be lectured to. Marty couldn't help but worry about his twin. Calvin seemed to be addicted to those grasshoppers.

oooooooooo

At around midnight, Marty went to use the washroom, when he saw that Calvin was lying on the floor unconscious. Tears filled Marty's eyes, as he was concerned about his twin. Marty ran up to his father.

'Dad! Dad!' Marty called out, urgently. 'Calvin is passed out on the washroom floor. I think he drank too many grasshoppers.'

'Why didn't you try to stop him?' demanded George.

'I did try to stop him,' Marty insisted, tearfully, 'but he refused to listen to me.'

'I'm sorry, Marty,' George said, sighing. 'I'll go attend to him. I hope we don't need to call an ambulance.'

Milton went to join George and Marty in the washroom. Fortunately, Milton was a physician, so he could easily tend to Calvin. George and Milton had lifted up Calvin's body, and propped Calvin up on the bench. Then Milton had fixed up some 'wake-up juice' to help Calvin regain consciousness. Marty sat next to Calvin, and he wept silently. He was so worried that Calvin might die.

'It's okay, Marty,' Milton said, softly. 'I just have to give him some of the juice, and then he'll be fine. Here, put the clothespin on his nose - and the stand back'

Marty did just that. When Calvin opened up his mouth, Milton had poured the juice down Calvin's throat. Then Milton stood back with Marty. Suddenly, Calvin stood up, opened his eyes, and jumped up.

'Wah! Hot Hot!' panted Calvin, as he ran over to the water basin, and dunked his head in it.

Marty and Milton had lifted Calvin up, and looked at his face.

'He's still out,' Marty said, quietly, as a tear slipped down his face.

'Oh, that, that was just a reflex action,' Milton explained. 'It's gonna take a few more minutes for the stuff to really clear up his head. He'll be fine, though.'

'I hope so,' Marty whispered, as another tear rolled down his face.

Marty and Milton then began slapping Calvin's face, hoping to wake him up.

After about ten minutes, Calvin woke up and exclaimed, 'Whoa!'

'Calvin! Calvin! Are you okay?' Marty asked, his voice snagging on a sob.

'I think so,' mumbled Calvin. 'Whoa, what a headache!'

Then Marty held Calvin tightly, as he wept silently.

'Wha-what's wrong, Marty?' Calvin mumbled.

'I was so worried you would die,' Marty said, quietly, as tears were rolling down his face. 'I was so worried about you, Calvin. I warned you that something like this might happen.'

'You're right, Marty,' mumbled Calvin. 'You're right. I should have listened to you. I guess I just got addicted to those grasshoppers.'

'Will you be okay, Calvin?' Marty asking, sniffing a bit.

'I'm just a bit tired,' mumbled Calvin. 'I'll be fine, though.'

'Good! Good!' mumbled Marty, as he hugged his twin. Then Marty wiped his face with the back of his hand, and helped Calvin up.

Then George set up a cot, as Marty and Milton had helped Calvin walk over. Marty had tucked Calvin in, then he kissed Calvin's forehead.

'Good night, Calvin,' Marty whispered.

'Good night, Marty,' replied Calvin. 'I'm sorry I didn't listen to you earlier.'

'Just try to get some rest, now, okay?' Marty said, softly. 'I love you.'

Then Marty gave Calvin one more kiss on the forehead, before turning out the light and leaving the room.
