Cheech & Chong's Next Movie (1980)

Visible crew/equipment: When one of them is using the bathroom - out of the bathroom window and it sprinkles on his neighbor's flowers, watch when the camera view goes up because you can see someone squeezing a rag onto the porch banister to look like his pee.

Chong: I dig it, man. It's good. But you know, while you were singing that, I came up with another song, man.
Cheech: Oh, yeah?
Chong: Yeah. It's like the same thing, only different.
