Joke:Mother-In-Law

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