They get infected by a bizarre virus and have to be -- oh, you'll see...

"Bad news, Bones," said Seeley Booth. "The FBI is sending you a body that we believe has been infected by the legendary Jackpot Virus. I hope you and your staff take the appropriate precautions."

"We always take precautions," said Temperance Brennan. "And anyway, I always thought the Jackpot Virus was a myth. "

"It may have once been," said Booth, "but right now, it isn't. We already had two female agents infected by it and we came this close to having a third one infected as well. So be careful. Have only your male staff members work on the body. As far as we can tell, the virus only affects women."

Brennan hung up the phone and shrugged. "Whatever," she said. "I really wish Booth wouldn't presume to tell me how to conduct my own business. I'm not an amateur, you know."

"What's the Jackpot Virus?" asked Brennan's intern, Daisy Wick.

"It's a mythical virus allegedly invented by some biotechnician who read too many science fiction stories," said Brennan. "Supposedly it turns any human female over the age of puberty into a wild-eyed exhibitionist the minute she is exposed to it. Its existence has been debunked by experts but you still hear rumors about it every now and then."

"So I guess we should be careful then," said Wick.

"Of course," said Brennan. "But no more than we'd ordinarily be."

The actual delivery of the corpse was uneventful and so was the subsequent autopsy. It wasn't until Brennan changed out of her hazmat suit that she noticed anything awry.

"I probably should have this suit burned," Brennan said apropos of nothing.

She silently took it off and gave it to Daisy Wick for disposal.

"Okay," said Wick.

"And this lab coat as well," said Brennan.

"All right," said Wick.

"And this dress."

"Wait a minute..."

"And this slip..."

"Er, Dr. Brennan..."

"And I don't really need this bra at my age. Nor do I need these panties. After all, it's not like concealing my vagina from public view is going to improve my analytical skills..."

"DR. BRENNAN!"

Dr. Brennan paused in the middle of taking off her stockings and just stared at Daisy Wick. "Really, Ms. Wick! To make such a scene in public! What kind of scientist are you?"
