S4·E18 Reese's Party

When Hal and Lois go out of town for a "last chance" getaway before the baby comes, Reese has a big bash that gets out of hand. College-age thugs show up, cancel the party and set up a drug-making operation in the garage. All Reese and Malcolm can do is knuckle under. The good news is, Dewey's not around. The bad news is, his baby sitter is Lois's annoying co-worker Craig. Meanwhile, Hal and his very pregnant wife are off at a romantic retreat---feuding.
