I have seared into my memory a specific scene from Third Rock From the Sun, in which Harry reveals he is wearing a lobster claw-shaped oven mitt, and declares "Lobster claw!".
Details I'm less sure of:
I think Tommy is also in the scene, and it may be in a kitchen or the kitchen section of a shop. Harry probably then lunges at someone with the claw.
Does anyone know what episode that is in?
