I've seen people use legos in uncreative ways. This kid I knew (of) would build whatever model the legos were intended for, and nothing else.
I would build robots with my technic legos, using home-made servos. I rarely built the model the legos were intended for. The one exception being the "Chassis" set which was a huge model of a car with engine, transmission, etc. As soon as I built it, I turned it into a radio-controlled car (although it was very slow).
As for humor, there are different kinds of humor. Humor seems to be our way of dealing with discomfort, and there are as many kinds of humor as there are kinds of discomfort. I tend to prefer irony (which deals with the discomfort of logical dissonance), satire, sarcasm, and tragic humor (which I can't seem to find a term for). Some people think I tend to use scatological humor, but that has more to do with repartee.
