^^ I'm glad I'm not the only "adult" who appreciates the line
I keep one at my desk in my home office to keep my hands busy when I'm on a tedious conference call. A full transformation will break your concentration, but these 1-steps are just simple enough to keep you awake while still being able to focus on work.
I feel that if they wanted to, they could add a little more articulation - knee joints would totally be possible. It's too bad there isn't an "advanced" line for this. I feel that just as much engineering (if not even more) can go into a figure that requires everything to fall in place in just one motion, so it's pretty impressive.
