Eastern Canada Puns

I am a cashier at Publix and had a guy and his wife come through my line. Upon ringing up his milk I asked "do you want your milk in a bag?"

Dad: "No thanks, I find it easier to take it home in the jug it came in!"

Dad's wife: "Dammit Phil, you say that every time we get milk."

Apparently, even after saying it every time, it still makes him chuckle.
