It's funny so long as it's good natured humor, and they are grown up enough to take it that way. As for me, I'm going to send one to all the guys in my league and tell them that's where they should play this year instead of taking on real men like myself. Nothing like getting the trash talk started early! Last year I had to assign a name to one of the teams as he refused to submit one as requested, and he wound up with The *Gay Pride Marching Band as a penalty for disobeying the rules!
*Not that there's anything wrong with that!
