Mr Bupkis is an anthropomorphic dog.
Description[]
A perpetually-sullen, Eeyoresque man, Mr Bupkis was a contestant in 1963 on Will Woofer's star TV game show Answer This. There, Bupkis seemingly made an utter embarrassment of himself, failing to answer such questions as "How old is a 90-year-old geriatric?". However, it turned out that Bupkis's litany of "I don't know"s was actually the expected answer.
Behind the scenes[]
Mr Bupkis appears in the 1963 story TV Trickery as a bit character.
