"Can You Dig It" Joke Help? Cant Remember Whole Thing.

So there is this joke I remember my friend's uncle telling us growing up that always cracked me up. I can remember part of it, but was wondering if anyone knew of the joke and the entire thing. Two verses I remember

"I'm a chink from the sink you can suck my dink can you dig it, can you dig it"

"I'm a nigga from the grass you can suck my ass can you dig it, can you dig it"

Then theres a white guy too I think and some story line to it as well.
