I loved Showbiz when I was a kid, way better than Chuck E. Cheese. Seriously, who wants to eat at a place who's mascot is a rat? Why not get some roaches to sing back up for him while you're at it.
This is also the guy that played the alien in "Alien", coincidentally. When Geiger wasn't given the gig for Alien 2, this guy refused to play the part in protest, and it was given to someone else.
Oddly, that actor died in a bizarre pizza restaurant accident 5 years later.
