Old problem

[topogigo]

A school boy is sitting doing his homework while his dad watches the football.
Dad asks his son
"What homework are you doing son?"
" Maths dad" his son replies.
" What's the question son?" dad asks.
The son explains.
"I am trying to find the lowest common denominator"
Puzzled dad asks.
" Haven't they found that yet? They were looking for that when i was at school!"
