When I was just learning to read, I thought the "No Loitering" sign said "No Lottering" as in playing the lottery and people who bought lottery tickets couldn't go there to wait for the numbers to be announced.
At another point, I was positive the word "loitering" had to do with some kind of inappropriate or obscene behavior. I'm not sure exactly what, but it just sounded that way to me.
