No, Virginia, that's not really Santa Claus! His name is Silenus Honey (not to be confused with my God, Silenus, Father of the Satyrs) and he's an actor living in Los Angeles. Perhaps you recognize him... He was the cook in those Pace Picante commercials ("NEW YORK CITY?!?!?!?") and also made an appearance in REM's music video "Losing My Religion". If you'd like to write to him, you can drop him a note at silenus2@earthlink.net.
Also, just for fun, check out claus.com and try to find the hidden homoerotic elements.
