A small farm boy named Little Johnny was milking his cow when all of a sudden a bull came charging toward him.
As horrified workers nearby watched, Little Johnny calmly continued his milking.
To everyone’s astonishment, the bull stopped a few inches from Little Johnny, turned around and walked away.
‘Weren’t you afraid?’ one of the workers asked Johnny.
‘Not at all,’ the Little Johnny replied,
‘I knew this cow was his mother-in-law.’
