I know that a lot of people say that. Not just kids, but I do think that it was wrong for you gym teacher (key word) said that. I don't think that the people that say that are using it to make fun of the mentally challanged. I think that the retarded people are really nice actually. Way nicer than some people I know, so I never make fun of them in any way. I know that we had a retarded person in our school, and she was always so friendly, and always ready to say hi.
