An aside on cultural appropriation

I am super sensitive about racism, especially the implicit racism in mainstream culture which always makes me prickle. Why do I find this not racist and actually the funniest thing ever? Is it that the funny overrides the offense or that it's such an over the top caricature that it crosses the line into absurdity? Or is it, as Zizek argues when you can make racist jokes and for them to be funny to everyone have we truly gone beyond racism as opposed to the politically correctness prohibition on offending anyone?
