How do you write a kick ass funny joke? Sometimes it seems they write themselves huh? They just come out of nowhere and bam!- there it is.
The topic is hot, passion is high, just the right associations are there, you simply try to steer clear by using as few as words as possible and deliver in character/attitude the surprise punch. Zing!!!
Come to think of it, that's how you write a kick ass funny joke. Phew!..that was easy...they do kinda write themselves if you give them a chance. Jokes are there, they want to come out and play, best thing you can do is try not to get in their way.
