Now your taking this out of context!
He didn't say never try to make a joke did he?
Just stop trying to use your as you call bits of "fun", in which are rude, offensive, and there is no point in saying them.
It's like saying a joke when your the only person who laughs, it's sad, and the fact that you find saying offensive remarks the most fun of all is just amazingly sad.
longstory, short, get rid of the dodgey posts, but don't be afraid to crack a joke once in a while.
If you got at all offended by this, then as one of your former post says, it's your problem.
