I'd sig that I call dibs
I don't see how it's that bad. Just cause he's famous doesn't mean he can't joke. I made a similar joke at school in front of a lot of people, some of which were Japanese. The public needs to lighten up a little and find something better to do than bitch about a famous person making a joke if you ask me.
I'd rather be sexually attracted to other men than be 50 cent.
