Hiya! I know I'm supposed to be working on Prongs Rides Again, but this one forced its way into my mind. For all of y'all that hate Mountain Dew (including me, funnily enough), you might or might not like this story.

Disclaimer: I do not own Harry Potter or any of its characters. I do not own Mountain Dew (I'd rather own Dr. Pepper), or its trademark slogan.

Summery: James introduces Sirius to the Muggle drink "Mountain Dew." Do not read if you don't like hyper people. Part I of the Dew Trilogy.

Part I: Crazy at First Taste

Quietly, James Potter lugged the twelve-pack of soda to his dorm room. It was hard trying to lug the thing along while wearing his Invisibility Cloak, but it was doable. His mother had just sent him his monthly allotment of his favorite Muggle soda. Not matter what, wizard kind just couldn't seem to duplicate the properties of Mountain Dew. So Mrs. Potter kept a few Muggle pounds handy to buy it every month for James.

James managed to get the twelve-pack all the way into the dorm without making a sound. He gently started to push the Dew into its hiding place under his bed.

The lights came on, revealing Remus, Peter, and Sirius, all in their pajamas, all in their beds, and all frowning at James.

"See, I told you he was sneaking out!" said Peter. The Marauder's Map was clutched in his hands.

"Snitch," muttered James while thinking, So that's where the Map went. No wonder I couldn't find it. He straightened back up, taking off the invisibility cloak as he stood up.

"What's that?" asked Sirius, sliding off his bed to the floor. He pulled the Mountain Dew out of its no longer safe hiding spot.

"'Mountain Dew'" he read aloud. "Is this that Muggle drink you've been sneaking in?"

"No. Wait, how would you know it's a Muggle soda?"

Sirius snorted. "I've been around magical drinks all my life, Prongs. If I haven't seen it before, that usually means it's not magical."

James's face took on a blissful expression. "Maybe not to you, but it's better than butterbeer."

"Better than butterbeer?" repeated Sirius. "It must be pretty good then." He opened up one of the ends of the box, and James snapped out of his self-induced trance.

"Padfoot, what are you doing?"

"I want to find out what's so special about this drink. Duh." He finally managed to get one end opened, only for the cans to spill out onto the floor.

"Be careful, Sirius!" said James. "You shake up one of those things, and it'll explode in your face!"

Sirius picked up one of the cans and looked at the top. "How do you open it?" James showed him the proper way to open the can. The drink fizzled as it was exposed to the air. Sirius sniffed it and sneezed. "The thing went up my nose!"

"Drink some, Padfoot," said Peter. The moment Sirius did, everyone wished he hadn't. His eyes widened and his body started shaking like Remus's did when he was transforming. Sirius had drunk half of the can in the first swallow, instead of just a little bit.

"Oh, no," muttered James. He recognized a caffeine high when he saw one.

"Do you like this stuff? I know I do!" said Sirius very fast. He suddenly transformed into his dog form and began running around the room at top speed.

"What did you do to him?" shouted Remus as Sirius shot over his head.

"It's the caffeine!" shouted back James. "He drank too much! The drink is loaded with the chemical! The only thing we can do is wait for it to wear off."

"How long will that take?" asked Peter, squeaking in terror.

"Probably a couple of hours!" said James, ducking under his bed.

For five hours, from midnight until 5 a.m., Sirius literally bounced off the walls, sometimes in his dog form, sometimes in his human form. Twice, Peter had to transform and find himself a small hole to hide in to keep Sirius from tossing him up in the air like a toy.

When five o'clock came, however, Sirius finally started to slow down. For a minute, he stood in the center of the room. Then he collapsed out of exhaustion. Convinced it was safe, Peter came out of his little hole and transformed back. They levitated Sirius onto his bed, and left him there. As they went down the stairs to the Common Room, James whispered, "Let's just tell the teachers he's out sick. He's gonna wake up in a few hours with a giant caffeine hangover." Remus and Peter agreed.

They never gave Sirius Mountain Dew ever again, and James never brought the drink back on Hogwarts grounds for the rest of his school years.
