"How dreadful!" cried Lord Henry. "I can stand brute force, but brute reason is quite unbearable. There is something unfair about its use. It is hitting below the intellect." ~ Oscar Wilde - The picture of Dorian Gray
I love puns and like Athenian200 mentioned, I always find even the smallest ones to be hilarious. I like people who pick up on things quickly enough to make a pun. People like that seem to be very clever, which attracts me. It's the main reason that made me notice my lovely INTP... Although I must admit that INTPs usually don't have the panache needed to avoid getting exasperated groans.
oh god. my father is an ENTP... puns pour out of that guy like bullets from a machine gun. it doesn't even have to be a phrase. this past halloween he wanted to be "flash gorton", which i'm guessing is going commando underneath a yellow poncho. luckily we had no yellow ponchos... god damn.
