A man was helping one of his cows give birth, when he noticed
his 4-year-old son standing wide-eyed at the fence, soaking in
the whole event. The man thought, "Great...he's 4 and 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." gasped the still wide-eyed lad. "How fast was that
calf going when he hit that cow?"
