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 UPS guy wants to buy Mom!'
