Isaiah has a habit of opening the compartment beneath the gas fire place and playing in the wires.
Joey calls him Mr. Fixit.
Actually, he points at him and yells, "Miiiiiisterrrrr. Fix-It."
How appropriate. The name, not the playing in the wires.
*For those wondering, Mr. Fixit is a Richard Scarry character who is always fixing things. The problem with Mr. Fixit, is that things are worse when he's done with them, than they were before he "fixed" them.
