"I was going to have a few comments on the other Democratic presidential candidate John Edwards, but it turns out you have to go into rehab if you use the word 'faggot,' "
This a funny joke. Is it a little crass? Yes but still funny.
A tranny calling someone a faggot? More ironic than funny
Lets turn the joke around and see if its still funny. "I am on this thread to talk about Ann Coulter but you have to go into rehab if you use the word "tranny" so I will have to pass."
See its not funny because unlike "faggot" you don't have to go into rehab if you use the word "tranny".
