Main character in the 1950s Western television series Have Gun, Will Travel. Played by actor Richard Boone, his card read "Wire Paladin, San Francisco". The surface meaning was that this is how one reached Paladin to purchase his services as a gunfighter, but I recall reading in an article about the series years ago that it is also a pun. The man's first name was actually "Wire".

Please bear in mind that I have not been able to confirm this elsewhere.
