It is almost unreasonable that Glee should be able to pump out not one but several stupendous and rewatchable professional musical numbers every week. What television show has been able to do this, (not counting Buffy because that was just a single, very special episode)? None! Hell, there are *movies* that have been made with huge budgets that cannot seem to squeeze out a watchable musical number, let alone two or three. It's really jaw-dropping how good these people are.
