Ginger felt a sudden wave of nausea when she got out of bed that morning. That's strange, she thought. I hardly ever get sick.

"What's wrong, Ginger?" asked Mary Ann. "You're as white as a sheet!"

"Why, I don't know!" Ginger exclaimed breathlessly. "Suddenly I just feel so dizzy..."

"Come back and sit down!" Mary Ann's maternal instincts suddenly kicked in, and she helped Ginger to a chair. "Let me bring you some water!"

Ginger picked up a large leaf and fanned herself with it. Mary Ann brought her the water, and she took a sip.

"You go ahead and have breakfast with the others. Tell them I'll eat later if I feel like it," Ginger told Mary Ann.

The others were all very concerned about their friend.

"Hopefully it's just a minor bug and she'll be better soon," said Mrs. Howell.

"I'll check her right after breakfast," the Professor said. After they had finished eating he went into the girls' hut, where he found Ginger lying in bed awake.

"Mary Ann told me you weren't feeling well," he said.

"When I got up this morning I just felt so funny," Ginger told him. "First I felt like I was going to be sick to my stomach, and then I felt like I might pass out."

"Have you eaten anything unusual lately?"

Ginger shook her head.

"Have you been getting enough rest?"

Ginger nodded.

"How has your monthly cycle been?"

Ginger gasped with surprise. "Why, I haven't...I missed last month, I suppose..."

The Professor's expression was grave. "Ginger, if I didn't know better, I could almost swear that you must be..." His voice trailed off. "But since we know it can't be that, I'm really at a loss...I'll go back to my hut right away and consult my medical books; maybe they'll shed some light on the mystery..."

He was almost out the door when Ginger finally got up the nerve to call to him.

"Oh...um...Professor?"

He glanced back questioningly.

"Actually, there is a chance that it could be...that."

The Professor gaped at her in disbelief. "But...which one of us, Ginger? I know that it couldn't have been me, and Mr. Howell and the Skipper both seem highly unlikely, so that leaves...Gilligan?"

Ginger shook her head. "Professor, remember those Russian cosmonauts who landed in the lagoon a little over a month ago?"

The Professor nodded. "Igor and Ivan. As I recall, Igor took quite a shine to you."

"I tricked him into leaving his capsule unattended so that you and Gilligan could search it," Ginger continued. "We went for a walk on the other side of the island. He asked if he could kiss me, and then one thing led to another, and...and..." Ginger, blushing fiercely, was unable to look the Professor in the eye.

"I can't believe it, Ginger." The Professor sighed with frustration. "How could you have been so careless?"

"I didn't intend for it to happen," Ginger said innocently. "It just...did."

The Professor just stood there, shaking his head helplessly.
