While I was doing laundry Tim was keeping me company. All of a sudden he said, "I take my head off today." So I said, "If you take your head off what will you do for a head?" Then he replied, "Get a crab hand....get a crab hand and Grab You!"
At this age it's probably pointless to tell him that if he wants to grow a crab claw he should probably remove his arm and not his head. All he cares about is being able to pinch people...who needs to a head, right?
