There is supposedly at least one tattoo studio in the continental US which has, in amongst all the stock designs on the walls, the Chinese for "I'm so stupid that I don't know what this means."

The person who mentioned this was American-Chinese, and asked the tattooist why this was up on the wall. The tattooist replied that it was there to catch idiots who just picked designs
which they thought looked cool - and that if someone was stupid enough to get a phrase which they didn't understand tattooed on their body, he'd do it.

Apparently he'd already put the design on several people, too - if  they'd have asked him what it meant, he'd have told them.
