I used to work security with a couple of Black guys. We were friends too. The smaller one was a wise ass and also a stand-up comic. I would enjoy using Black expressions and sayings but make myself sound like how Richard Pryor imitated how White people spoke. He seemed to enjoy it somewhat having a confused smile.
The bigger one I would basically bring along and frame for stuff I did. He'd barely grab a guy by the shirt that ended up beaten up really bad then I'd turn and say, "Holy crap! Look what you did!" I got a little carried away one night then I did my Dave Chappelle imitating a crooked White cop impersonation and said, "Hey Johnson, sprinkle a little crack on him and let's get the heck outta here!" I miss that big oaf.
