Arbiter Samuel Sandini is clearly Sammy Davis, Jr., from Laugh-In:

Um, Laugh-In is the least of his credits.

I thought it was him and looked for pictures of the rest of the Rat Pack, but the other arbiters don't look like them.

El Jefe's video link does show the specific character he was playing which this character is based on. 

Good catch!

Apparently this is where "Here comes the Judge" comes from?

I suppose they're likely all comedic takes on judges. Would the one on the viewers left be Harry Anderson from Night Court?
