Summary[edit | edit source]
Malcolm, Reese and Dewey prepare for the arrival of their babysitter. Assuming it's another old woman caring for them, the boys plot a heinous prank that will send her running. To Malcolm, Reese and Dewey's surprise, their babysitter is a sexy teenager named Patty.
Hal and Lois go out of town to a convention, where Hal keeps picking fights with a coworker who stole an idea he had. The two men get into a fight and are arrested by the cops. Lois had enough and tells him off how immature he's behaving. She give Hal a choice: He could take his anger out on the co-worker and they could go to jail. Or he can take his anger on her and they can use it to have an outlet for sex. Hal tells Lois that isn't fair of her to use this in an attempt to get a sultry mode on, but later agrees to avoid jail time.
Back at home, the boys compete for the attention of Patty, an old friend of Francis (who doesn't know that she is gorgeous now, having been obese while he was going to school with her). She finds Dewey too adorable and barely notices the other two. Malcolm and Reese become jealous and try to get Francis' help.
