According to IMDB, he was in a comedy short called "The Glowing". Other than that, he's only listed as a producer (Ghost Hunters), a musician (he played piano on an episode of "Spirit Hunters" ... way to really stretch the envelope there), and as appearing as himself on Talk Shows and as a "paranormal expert" (again, himself) on "Ghost Hunters" and similar shows.
It doesn't mention him being on Happy Days. He was born in 1974, so it's theoretically possible he could have been (the show ran from 1974-1984), but it would almost certainly be listed on IMDB if he had.
