One interesting thing about this is that people have problems with it at all. I think it's a psychological thing - you take some numbers, and they almost add up to some other number, and because it almost fits, you can convince people that it should add up. If you'd tell the story like this, I doubt it would work at all:
"3 men go into a mo ...[text shortened]... R27, add the R7 that the bellboy kept = R34.
Where did those 4 extra Rands come from?"
