I submitted my first joke (not this) to rec.humor.funny, and THEN, being the conscientious guy that I am, started reading the submission guidelines. Then I came upon the following rule: o) If I reject your joke, keep trying. Most people get rejections, and even the people you see who have been published multiple times get lots of rejections. I KNOW this joke is going to be accepted by the powers that be, because I will keep sending this joke to them till they accept it.
