Falling Down

Roseanne interviewing Sandra Bernhard:

BARR: What makes you laugh?
BERNHARD: Well, it's really a myriad of things, but usually it's something that's very organic. It's something that happens on the street.
BARR: Like fat people falling down?
BERNHARD: No, no… [laughs]
BARR: That really cracks me up. It's terrible.

Ah yes, fat girls falling down is funny.
