Come on, stand up comedians are the perfect source for canned material, stories and such.
You don't even need people to think you made that shit up, just say "Did you see that Kat Williams special?"
"This shit here! This shit here nigga! This shit! Right here! This shit right here nigga!"
"This shit's called deaf!"
"You mean... if I hit this shit, Imah die?!"
"NAW nigga! DeaF! You take two hits of this shit and you can't hear SHIT!"
"Nigga... I got shit to do today!"

I mean just youtube or on demand some stand up comedians, internalize their deliveries if your not funny, they've done all the work for you man!
Obviously, your going to want to know a variety of routines, I wouldn't suggest acting out Kat Williams with a classier class of woman.

One helpful hint, if you can find the spontaneaty (Whatever that word is..) then before you bring it up, just remember how you felt when you first laughed at it.

It's mirror neurons, like getting horny to create sexual tension.
(Think about it, now getting horny is like a super power! lmfao)
