I don't think we'll ever see a better version of the good-hearted dumb guy. He always made me laugh on "Newhart" and reruns of "The (old) Bob Newhart Show". My dad loved him on the the old Steve Allen show and my nephews laughed like crazy when he was on "The Suite Life of Zack and Cody".
I'm glad he'll live forever in reruns, practically every night, somewhere.

The episode where he is first mentioned only make reference to the fact that he is perceived to be in the pocket of mining interests and is not particularly swift on the uptake. But no actual source of the "Bingo Bob" moniker.
