sigh We miss out on so much humor in America because of this Puritan stick up society's ass. >
I like one that read "We don't care. Come on in and pee."
heh heh... cute... Curious: is there a significance of the red & black colors?
Colors have significance in Thailand, but only in relationship to the days of the week and when you were born.
In this case, the woman is pink, so might be catering to foreigners, who often see pink as feminine, since it shows pictures instead of the usual Thai language sign.
Thai men commonly wear pink, but some are aware of Western customs.
