Q: What’s Santa’s dog’s name?
A: Santa Paws!

This is a silly christmas-themed joke. The aptronym Santa Paws is appropriate to a dog (or any animal that has paws for that matter.)

Paws and Claws are rhyming words, and perhaps this could be considered a pun (although paws and laws don't really sound that much alike.)
