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?!?!
According to one source, the first effective silencers for guns were actually designed to be sound mufflers for machinery. Also, I’m surprised I didn’t get any complaints about a comic strip that may involve guns.
