A farmer had a cow that was calving and having
problems. So the farmer worked and worked, finally
got a rope around the calf but still couldn't get
the calf out. About that time a young boy came by.
The farmer said, "Son, grab this rope, help me pull,
and don't ask any questions." So they finally got
the calf out. The young boy stood around for a few
minutes and then asked, "can I ask you just one
question?" The farmer thought he deserved to be
allowed to ask one question and told him so. The boy
asked, "how fast was that calf going when he hit
that cow in the rear?"
