LEGO Techniques - The Man Car

I suppose this technique has more to with a particular part than the whole thing.  But I generally post about parts without much in the way of examples.  Here's an actual example.

In building the Repair Lift, we began to have a little fun with Bill.  I was showing the girls how the wrench would fit on the head stud (ow...).  Then I put the pick-axe handle into the hollow stud on top of the head (double ow...).  Then I got the bright idea to but the wheel holder (with hollow tube) down over the neck and place the head back on top (super ow...).  Poor Bill.

I then left him at that and went on to dink around with something else.  Less than a minute later one of my daughters had taken the other wheels and placed them on Bill's feet.  He was now four wheels waiting to happen.  Place has little wowzamajiger in his hand and this guy was ready to roll.

Creepy?  Maybe...
