Pac-Man Trivia

As per Scott Pilgrim:

Did you know that the original name for Pac-Man was Puck-Man? You'd think it was because he looks like a hockey puck but it actually comes from the Japanese phrase 'Paku-Paku,' which means to flap one's mouth open and closed. They changed it because they thought Puck-Man would be too easy to vandalize, you know, like people could just scratch off the P and turn it into an F or whatever.

As per Yahoo News:

That theme continued with the game's name. In Japanese, "puck puck" is akin to the U.S. saying "munch munch". So the original name - Puck-Man - translated as "Munch man". (A savvy Midway Games official changed it to Pac-Man when the game hit the U.S. to discourage vandals from shaving off part of the "P," thereby creating an obscene word.)
