On Family Ties

The following is a conversation between my dad and Max about my two brothers:

Grandpa: "Max you're going on vacation with Mommy and Daddy next week"

Max: "No I'm not"

Grandpa: "Yes you are. You're going to Toronto to visit uncle Nick"

Max: "You know him?"

Grandpa: "Yes I know him, he's my son"

Max: "Really? That guy?"

Grandpa: "Yes, and uncle Josh too, he's my son as well"

Max (in disbelief): "Really? You know uncle Josh too???"
