I read about an incident years ago in which Chris Kattan accidentally ripped open Cheri Oteri's top in a dress rehearsal sketch. Lo and behold, they actually released the incident on DVD (on "The Best of Chris Kattan", though it should be on "The Breast (excuse me)
Best of Cheri Oteri")! I'm a bit surprised that they released it, actually, since it seems like the kind of thing they'd want to lock away in a vault, but hey, I'm not complaining.
The two funniest parts are the fact that neither one of them realizes what happened for a good few seconds, and then Cheri's embarrassed reaction in which she mouths "Fuck!".
Video and collage made by me, capped from the DVD.
Enjoy
