Can you imagine how much superglue they used to keep those instruments in their hands? I bet they just used chimps like disposable diapers back then, after the shoot they were taken out back and put out of their misery.
It's hard to hate anything a chimp does (unless it's biting off your fingers or tearing off your face).
@The RandF Workhorse Nah, glue falls apart when they sweat. They nailed them on.
