You Know The Voices: An ant, an aardvark, & the Inspector play Hollywood Squares (not really)(1987)

 Of course, I'm referring to John Byner (The Ant & The Aardvark) and Pat Harrington (The Inspector, ex-One Day at a Time), with John in the center square position in this entry from season 1 of the John Davidson era.

Contrary to announcer Richard Stevens' pronouncement, One Day was off the air and in reruns by the time this episode aired in February 1987.
