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.’
