Bingo the Chimp on The Abbott and Costello Show gave Lou Costello the jitters and the chimp sensed it. It would always make a grab at Lou and never quite seemed to be in control in Costello's presence. Bud Abbott, on the other hand, had absolutely no fear whatsoever of the animal and it appeared to be considerably more docile in shots that included just Bud and Bingo.

Of course, as most of us already know, Bingo put the kibosh on her (yes, Bingo was female, although it wore a replica of Costello's wardrobe) own career by finally biting Lou, resulting in her immediate dismissal from the cast of the show.
