Futurama and Big Bang Theory. Family Guy, American Dad and Southpark too. I've probably seen too much of The Simpsons and Everyone Loves Raymond.
We have NO good music shows at all these days. Back in the day you could get all sorts of cool bands on TV, now it seems to be mostly hip hop with people gyrating, plastic pop or grungy indie. Fine ... but what about some variety?!
GTK was the best show ever http://en.wikipedia.org/wiki/GTK_%28TV_series%29
