i saw a crippled kid getting picked on the other day   he got upset when i told him to stand up for himself .
That is a pretty insensitive joke to make towards people with disabilities.
No, I don't. It's not my fault he wasn't able to stand on his foot.
Making jokes about kids who are crippled is a pretty insensitive thing to do. A better option may be to help the kid out instead of making jokes about them.
