This is some of the most bizarre footage we've ever seen -- YOU GOTTA SEE THIS.
Leaving Paris Hilton's birthday party at Butter last night, Mickey went off on an unprovoked "pro-gay" rant -- attempting to crack gay joke after gay joke.
It was all a bit awkward, but things really got strange when Mickey dragged a random fan into the attempted gay humor, kissing him on the face and then telling him, "I'm gonna kiss you all night long."
The stunned fan's shocked and confused look says it all.
Rourke then says, "Don't we look good together? I should have been in that gay movie ... I should have been in Milk." Yeah, probably a good thing he wasn't.
Rourke did, however, peel off some cash to a homeless dude -- but even that exchange was just weird.
