No I don't find that funny, but I am not an American viewer. In fact I live in a more polluted/industrialized city than Pittsburgh, and it is coincidentally one of the sister cities you can find in the wikipedia page of Pittsburgh. Sadly the wikipedia page of the city I am in doesn't mention the air pollution anymore but it ued to mention it.
Oh well the czech one still mentions it, go to
http://cs.wikipedia.org/wiki/Ostrava#.C5.BDivotn.C3.AD_prost.C5.99ed.C3.AD
And have that part translated through google translator,

go to Environment, it still sucks though, the translation.
