The Cosby Show, Season 3

Vanessa:
Wait, Theo said that when you caught him and Cockroach smoking, you yelled so loud you cracked the walls.

Cliff:
Yeah, because those two were smoking, I knock on the door they go 'oh wait! Just a minute! Just a minute', so I open the door. They go 'Hello dad!' and 'Hello Dr. Huxtable', they've tossed the cigarettes under the bed still lit! Smoke's coming up, I ask a stupid question, I say 'have you been smoking?' they go 'Oh no' and smoke's coming out the side of their mouths, I say what's that? They say 'Oh well we were trying this very spicy beef jerky'. They're lucky I didn't crack more than the walls by yelling.
