Are you serious? Have you ever drank a beer?
I see them all the time at the beach, camping, etc... We always have tons of them floating around on the boat and people fight over the funny ones. I found the funniest coozie/koozie/cool cup/whatever you want to call it at some redneck store the other day... It's a deer with antlers sticking out of it. If I only had a picture of it... I can't wait to use it this summer.
