The Choir

In a certain institution for the intellectually impaired, Mick, a highly qualified musician was employed to develop a choir. He was a little intrigued to find that the inmates walked around all day tapping on apples with pencils, and when he tried to rehearse them, he found they continued to do the same thing.
They couldn't be stopped, so Mick the musician, now conductor, taught them how to beat time on their apples, and then proceeded to train them as singers. The results were remarkable; there was real talent there and soon the choir was performing at events all over by invitation.
Eventually a TV producer came to sign them up for a series, but he too was intrigued by the fact that, during choruses from oratorios and operas, in sacred songs or pop, the choristers would tap their apples.
However, it didn't seem to interfere with the quality of the singing, so he asked Mick to sign a contract.
'By the way,' said the TV producer, 'You'll need a good name so we can do publicity for you that's really catchy.'
'Sure.' said the Mick. 'We're the Moron Tap-an-Apple Choir!'
