Here's a summary of a funny pun I read yesterday on the 100 hour board (I'd link to it directly, but the site is down):
Q: Why hunters eat cotton tail rabbits, but not jack rabbits.
A1: It has to do with the jack rabbits being hares and that there are many superstitions associated with hares.
A2: Hunters aren't the only ones who don't eat hares. If you found a hare in your soup, what would you do? That's right, send it back to kitchen.
