We learned from Dave Chappelle's co-writer Neal Brennan that R. Kelly was plenty pissed about Dave's notorious "(I Wanna) Piss On You" sketch and sent his goons to a Common show in Chicago to confront Chappelle.

Dave has confirmed that story in the past, and he did so again earlier this week during a set at the West Hollywood Improv with Chappelle’s Show cast member Donnell Rawlings.

"His goons busted in my room. I don't know if it was his goons, but they sure did like him," Dave -- who sounds like he had a bunch to drink -- explained. 

"How you gonna do a video of me peeing on a b*tch like that," Kelly said

“How YOU gonna do a video of you peeing on a b*tch like that," Dave shot back.
