Ever notice that Pac-man looks like a disc or a puck? Puck Man was actually
the original name of the classic arcade game that we know as Pac-man. In
fact, Puck Man machines can still be found throughout Europe and Japan. For
the North American market, the name was changed from Puck Man to Pac-Man, as
it was thought that vandals would be likely to change the P in Puck to an F,
forming a common expletive.
