Young Son Growing Up...
A man and his young son are walking in the country when they pass a field of cows, the kid says 'look daddy, moo cows!' Dad says, 'You are a bit old to be calling them that, they are just a herd of cows'
Soon they come to a railway and a train passes by, little boy says 'look daddy, choo choo train!' The dad sighs and tells the boy to speak with more maturity.
Later that evening dad finds his son reading a book - 'hey son, what are you reading?' says dad. The boy looks at the cover and says 'Winnie the Shit'
