My roommate, Mal, is a huge fan of puns. This puts an enormous strain upon our relationship.
Her answering machine is always presented as a pun. Always.
The worst part of puns is when the punner pauses afterwards, asking with an idiot grimace on his or her face, "do you get it?" And then they proceed to explain the intricacies of some stupid phrase that you'll probably hear them utter two or three more times to other people throughout the lunch break, and with greater emphasis each time.
I mean, at least being ironic or newly antiquated means you don't have to follow it up with a stupid catch-phrase. Punners everywhere should just stop talking and start wearing Mickey Mouse tshirts.
