Madhouse (1990)

Newly hitched Kirstie Alley and John Larroquette just want to kick back and enjoy their swank new pad (and their big marital bed), but a swarm of house guests screws up their best-laid plans in Madhouse (1990). First John's cousin drops in with his wife in tow—they're supposed to stay for the holiday, but the missus is preggo, and an accident lands her stuck at the house until the baby arrives. Then Kirstie's sister and her son show up, the next-door neighbors muscle their way in, and the dream house becomes a waking nightmare. All this bedlam causes John to nearly come undone and puts Kistie's job on the line to boot. Apparently it prevents her from doffing her duds too, because the closest she gets is baring be-bra'd spuds. Get rid of those guests ASAP and make with the T&A already!
