I learned this fact while researching wombats for a book I was writing that everyone who has read loves and still quotes passages back to me but, sadly, you will probably never see.
OK, the joke is good, but looking at the strip now I think maybe I should have left out Penn saying “Um” because the way I drew it too many people think it’s the bear saying it.
I think I thought of this pun as a kid, probably while watching Gunsmoke, but just never thought of how to use it as a cartoon. Aren’t you glad I finally figured it out?!?!
