Though I'm certain plenty of people already know this, after being mentioned in the movie Scott Pilgrim vs. The World; Pac-Man was originally named Puck-Man in Japan. Makes sense considering that he was shaped like a puck and the story goes that his creator was inspired by a pizza with a slice missing.
The reason the translation didn't stay makes plenty of sense. When Puck-Man was about to be sent to the United States, Namco and Midway feared that vandals would scratch out part of the P in Puck to become an F, thus creating an unsightly curse word that would cause parents to not let their kids play the F-bomb game. They wisely changed the title to Pac-Man and the rest is history!
