I screen printed the sentence, "It is impossible to lick your elbow" on a bunch of tote bags. Supposedly, 70% of people who read that sentence while in private try to lick their own elbow. I am intrigued with how people might react to reading it in public.
I have a handful left so if you want one, just email me. If you spot someone trying to lick their elbow, snap a photo and send it to me.
