Yesterday my 3 year old son walks over to me while i'm plastering in my living room, with his little watering can and says "Daddy, can you please fill this up for me again, Mummy's gone upstairs"
So I say (expecting him to tell me how good he's been etc) "And why should I stop what i'm doing, go all the way to the outside tap and fill it up for you, son?"
He looks at me dead staight and goes "Because it's empty?"
Hahahahaha fucking kids
