That's the funniest part of the movie.
"gat damn that boy can sang"
Clarence: You must be out your ******n mind! Joe Louis, the greatest boxer that ever lived. [to Akeem and Semmi] I'll be with you boys in a minute. He was badder than Cassius Clay, he was badder than Sugar Ray, and that new boy-what's his name? Mike Tyson?-looks like a bulldog; he was badder than him, too.
Saul: Vait a minute. Vat about Rocky Marciano?
Clarence: Oh, there they go. There they go, every time I start talkin 'bout boxing, a white man got to pull Rocky Marciano out they ass. That's their one, that's their one. Rocky Marciano! Rocky Marciano! Let me tell you something, once and for all--Rocky Marciano was good; but compared to Joe Louis, Rocky Marciano ain't s***.
Saul: He beat Joe Louis' ass.
Morris: That's right, he did whoop Joe Louis' ass.
Clarence: Joe Louis was 75 years old when they fought.
Morris: I don't know how old he was, but he got his ass whooped.
Clarence: Joe Louis had come out of retirement to fight Rocky Marciano the minute he was 76 years old. Joe Louis was always lying about his age. He lied about his age all the time. One time Frank Sinatra came in here and sat in this chair. I said Frank 'you hang out with Joe Louis, just between me and you, how old is Joe Louis?' You know what Frank told me, he said "Hey, Joe Louis is 137 years old." A hundred and thirty-seven years old!
