Inspectors visit the Primary school and take a group of kids to ask them questions about their schooling.
'How many pupils are there ?" asks inspector 1
"About 250,"replies the school Head Prefect.

'How many teachers work here?' asks inspector 2
Quick as a flash were Johnny responds...
"About half of them!"
Many a truth.....
