Is this joke offensive/morally reprehensible?

I thought this one was funny, I didn’t particularly like the other three. Offensive? Eh, not to me.

Hey, going one for four in a set of jokes I made up on the spot is high praise for someone who isn’t even a comedian. Thanks.

Aw, c’mon. Nobody has said that. Stupid racist jokes aren’t MAJOR HUMAN RIGHTS VIOLATIONS, they’re just stupid racist jokes. Don’t be so defensive.
