I am trying to find a comedy skit I heard about a black guy making a white guy his nigger. Does anyone know if this was a Pryor skit? If so where can I find it?

I remember a skit I think that Mr. Pryor did and I want to know if he did do the skit and what date he recorded it so I can get that album. The skit is about making a white guy his "nigger". Anyone know about it?
