Halloween fat costumes, offensive?

[wtchmel]

How do you all feel about the new halloween fat costumes i've seen kids wearing? They have a huge fat women and a sumo wrestler fat man. Do you find them offensive?
I'm wondering if i'm overreacting, doesn't this type of deal just perpetuate the fat person stereotype? Would you consider it the same as wearing 'black face' or dressing as a 'gay ken' ?
Curious........
