When Roy gets dumped after a date, he starts believing that girls go for "bad boys" and creates a fake profile on a dating site and, surprisingly, gets a response. Meanwhile, Jen starts flirting with a security guard.
Jen has her period and she starts to see the same symptoms in the boys. They say that it's impossible but they reconsider after they start having the same symptoms as Jen. They're even given their own website after talking about it online.
