I thought the same thing too and was also pleasantly surprised. In the past, I've always just found these machines entertaining, as opposed to funny. I never knew they were supposed to be funny; I always thought they were just supposed to be pointlessly entertaining ("Ooo what's going to happen next?!") but I definitely got a good laugh out of the end there. The guy certainly proved the hilarity of making the simplest task as ridiculously complicated as possible.

And I'm reminded of times in the past where I've unintentionally solved a problem in software engineering through a ridiculously complicated method where there was actually a much simpler solution unapparent to me. At the time, it wasn't funny; but looking back now, it certainly is.

I wonder how many times it took him to get it to work right, especially with the hamster likely being the most unpredictable component of the system.
