joke

A blonde teacher is on her first day at a new school and wanders out on to the playing field during her lunch break. she sees loads of boys running around, playing and having a great time but spots one boy all on his own, with no-one to talk to.

She feels sorry for him and walks over.

‘You don’t want to be on your own while everyone else is having so much fun. Why don’t you run up to the other end of the field and join them?’

The boy
replies …

‘Because I am the goalkeeper.’
