From 3rd grade till 6th grade I actually rode the shortbus to school, but not for the reason that you all think. I went to an accellerated school for smart kids (I hated every second of it). The bus that took us was a shortbus,
1/2 the bus was the accelerated kids, and the other 1/2 was the BD kids, who were thrown in thos school for violent behaviors and just plain nuttery, that were locked in the basement of our school (literally, the basement had metal detectors and stuff they had to walk through every day, thats where they threw all the BD kids so they wouldnt have to deal with em).
Anyway, it was quite an experience, because all of the accelerated kids would do crazy things and just blame it on the BD kids (rocking the bus, throwing stuff around, trashing the bus, etc, etc) Bus ride was usually very interesting.
To answer your question, yes, we made fun of the kids on the shortbus, we even got em in trouble a few times.
