The Birds and Bees

A man was helping one of his cows give birth, when he noticed his 11-year-old son standing wide-eyed at the fence, soaking in the whole event.

The man thought:

- Great...he's 11 and now I'm gonna have to start explaining the birds and bees. No need to jump the gun - I'll just let him ask, and I'll answer.

After everything was over, the man walked over to his son and said:

- Well son, do you have any questions?

- Just one Dad - gasped the still wide-eyed lad.

Just as the father is preparing his birds and bees story, his son asks:

- How fast was that calf going when he hit that cow?
