Heh, I really like this
New York Magazine ran a competition in which contestants were asked to take a well-known expression in another language, change a single letter and provide a definition for the new expression
Here are the responses:
HARLEZ-VOUS FRANCAIS - Can you drive a French motorcycle
IDIOS AMIGOS - We're wild and crazy guys!
VENI, VIPI, VICI - I came, I'm a very important person, I conquered
COGITO, EGGO SUM - I think; therefore I am a waffle
