I don't joke about 9/11, my jokes just have a tendency to crash and burn. Get it?
What makes you think joking about 9/11 is appropriate?
Well, since a plane was crashed into the twin towers, you can expect a joke about it to be disastrous. Like this one, for instance.
I just don't see how the deaths of thousands of innocent people can be a joking topic for you.
It's my birthday and if I want to make jokes about 9/11 I will.
I can't stop you, but I certainly don't want to hear the jokes and I'm sure most Americans wouldn't, either.
