Here's your totally useless fact of the day:

The 'fingers circle' gesture is widely accepted
as the American 'okay'
or 'I'm in agreement' sign, but it means
something quite different in
other countries.In Brazil and Germany, the
gesture is considered vulgar
or obscene. The gesture is also considered
impolite in Greece and Russia,
while in Japan it means 'money'. In southern
France, the fingers-circle
sign signifies 'worthless' or 'zero'."
