Sean inadvertently finds a fake ID in Lily's bedroom. Sean and Claudia confront their daughter about her rebellious behavior, but they get few answers. They decide to hack into her e-mail to find out more about Lily's trouble-making friends. While they are checking, an e-mail comes in from a ""SweetandNastee."" Sean responds, pretending to be Lily. SweetandNastee gives Sean an address to a rave party in Yonkers. Sean and Eddie go to the address which turns out to be a dry cleaners. Convinced the rave is really at the dry cleaners, Sean and Eddie try to gain access to the party but end up getting beaten up by the dry cleaners' owner. Back at home, Sean and Claudia confront Lily, but she slams them for invading her privacy. Turns out she knew they broke into her e-mail account because she was online at a friend's house when she saw her name logged in. Lily made up the rave to teach her folks a lesson about snooping.

To save for a dream vacation to Mexico, Sean and Claudia start working extra shifts at work. This leads to chaos at home, with Eddie raising the kids, Lily getting her tongue pierced, Jimmy becoming a bully, and Henry panhandling and eating out of the garbage.

Sean gets ticked off with Walt, who's playing Santa Claus, when he promises Henry a $350 Astro Jammer Battle Buggy for Christmas. So Sean responds by bringing violence to Santaland. Meanwhile Lily tries to figure out if the blurry giftcard on her boxershorts reads ""from Brad"" or ""from Dean.""

The Finnertys' plan to push Walt (Richard Riehle) back into the social scene backfires when he's social with a lady they don't like. Meanwhile, Lily fears that her bad behavior has thrust Brad into Kristina's arms.

The boys mock Sean when he can't get the lugnuts off of the car, leaving him to have his wife attract a trucker's attention to change the flat tire while he sits in drag in the backseat. Elsewhere, Eddie holds a garage sale at Sean's house where he sells off hot merchandise and his brother's possessions, and he welcomes the kids to partake in the sale. But Lily is mortified when Brad buys her old bra from Eddie, then boasts to the school that he and Lily have slept together.

Sean and Eddie hire strippers for the bar to help make ends meet -- then wind up being protested by the PTA. But what's most shocking is who set the PTA on their tails. Meanwhile, Brad asks Lily to break up with Dean. Lily doesn't want to hurt Dean, but agrees, only to find that he takes it far easier than she expected.
