Dad Joke Mug

Rainbow jumper. Rotary phone. A kid who's clearly delivered this line before and clearly enjoyed it.

"He's at your Mum's house."

The oldest joke in the book, on a mug, said with total innocence by a child who has absolutely no idea what he's just done to the room.

Available in Mum's house or Mom's house - because Dad jokes are universal, but spelling isn't.
