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.
