There's a clip on youtube somewhere, where he's totally fucked up on the Howard Stern Show, and mumbles something about two hits pauly made him do. Maybe it was three. They ask him to clarify and he claims up.

I dont know if he meant he was in on them or the actual trigger man. Or was lying. Or accidentally being honest because he was so fucked up on who knows what, or what. Just sayin, it's out there.
