It's Bud's 18th birthday, but everyone still treats him like a little boy. Does he stay at home for his birthday party with a pony and a clown or does Al have something else in mind for his "adult" son?

It's Al and Peggy's 20th wedding anniversary, but Peggy only wants one thing from Al....S-E-X. Meanwhile, Kelly and Bud win the "My Dinner With Anthrax" contest which means a house party for the trash metal band. But there will be no party unless they can get rid of mom and dad first. The answer? Tricking them into taking a Florida vacation that turns out to be a time share sales scam where the salesman won't leave them alone. Back home, the house party gets dull with no food in the house and 10 feet of snow outside.
