Well, I don't mean to stop using them ENTIRELY, just to stop using them when they're clearly inappropriate, like at Somber Gatherings of Great Importance (which are, of course, almost always where the greatest punning opportunities are to be found, making it the most difficult thing to quit).
Puns are fun but sometimes it's embarrassing if you just keep making bad puns and can't stop yourself!
