Why is it okay to make fun of a person's skin colour but not their size?
Reggie, the stand-up comic, made fun of the white guy at the comedy club, but you didn't see him shedding a tear and feeling sorry for himself. Sherman however, who is responsible for his own size (unlike the white guy who can't help his skin colour) gets all "boo hoo", even though he was quite happy to laughe at the other people Reggie mocked.
At least Sherman could go on a diet and stop stuffing his damn face. What could the white guy do to stop being white?!?
Welcome to today's world people. Where it's cool to make fun of people for being white, but a complete no-no to make fun of people for something they can actually do something about, their weight.
