little johnny again

[briggie]

Little johnny attended a horse auction with his father.
He watched as his father moved from horse to horse, running his hands up and down the horse's legs and rump, and chest.
After a few minutes, johnny asked, 'Dad, why are you doing that?'
His father replied, 'Because when I'm buying horses, I have to make sure that they are healthy and in good shape before I buy'.
johnny, looking worried, said, 'Dad, I think the postman wants to buy Mum ....'
