Is this article talking about it:
Summary – idiots at GameStop management decide that it would be a peachy-keen fabulous idea to dress their employees up in fat suites to advertise fitness games. Originally I was happy to see an article trashing the idea until I read it. The gems include such things as "First of all, I mean, come on. Who wants to buy a fitness game from a fat person?" The article has moments of positive ideas but in general I think the article is an Epic Fail.
Dances With Fat 
I totally agree with you. Things like this make me so mad. Would they have their employees black up? Or sit in wheelchairs? Of course not, and that would be wrong and offensive. So what makes wearing fat suits acceptable?
