[Richard O'Clery]

Farmer realised his cow's calf was breached, so he reaches his hands in, turns the calf and delivers it safe and healthy. Looks over his shoulder and sees his 5 year old son has seen the whole thing.

Farmer says, "Errr, do you have any questions about what you've just seen?"

His son says, "One question dad. Just how fast was the little cow going when it crashed into the big cow?"
