'Cheech & Chong's Next Movie' (1980)
It's hard to turn a stoner comedy into a franchise – those require a little too much follow-through. But Cheech & Chong pulled it off with the immortal trilogy of Up in Smoke, Cheech & Chong's Next Movie and Nice Dreams. And like the Godfather and Star Wars trilogies, this one peaks with Chapter Two – with some help from Pee-wee Herman. "Man, if you had a second brain," says Cheech, "it would die of loneliness, man."
Stoniest moment: After one toke over the line, Cheech loses his sense of time. "Man, I'm gonna be late for work again. That's the fifth time this week – and it's only Tuesday, man!"
