So my mum shows my 3yo boy this shirt with the question of "Can you read it? It says My Dads a...?"
My 3yo replies with gusto "TOOL!" 
My mum and wife fair wet themselves laughing 
How does he know!!?! 
We live in a town with a working port. My wife's parents were looking after our 2.5yo last week when a cattle ship was in. The mother in law asked my youngest "What's that big ship out there?" My youngest replied "it's a bullsh!t, that's what it is!"
Kids hey!
