As I've said a few times before, it's sometimes difficult to think of an original pun that hasn't already been discovered by one of the fifteen eleventybillion people on the internet. However, a google search of this pun netted far fewer results than I would have expected, and I was unable to find a comic/image that actually used it in a story of sorts.
I can't remember what I was trying to say. Oh, that's right. From now on, I'm not even going to google the puns I think of because I'm sick of being disappointed and crying myself to sleep. The best I can do is attempt to depict them in an original/slightly entertaining way (but I'll likely fail at that too).
That said, if you come here expecting good, original jokes, you're probably in the wrong place.
ALSO, SHUTUP THAT'S WHAT BEAVERS LOOK LIKE.
