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.’
