What did one retarded boy say to the other? Nobody knows, but it sounded hilarious.
Are you mocking the mentally handicapped?
Yes, it's funny because they are retarded and they aren't supposed to say anything but they still do. It's funny to see them not live up to their potential.
I don't think it's funny to mock the mentally disabled, saying they can't speak well. That sort of comment can be really hurtful.
