There are several finales on tonight, and they are mostly pretty dark and depressing. But there is some comedy to be found on NBC. On "Community," Senor Chang gets replaced when the college finds out he doesn't actually have a teaching degree. On "Parks & Recreation," Rob Lowe (left) plays an auditor who comes to Pawnee to slash the budget. And on "30 Rock," Liz needs a date to Floyd's wedding so she revisits old flames hoping for a love connection. Michael Sheen and Jon Hamm return for that.
And now, the dark stuff...
Vampire Diaries (8pm, CW) - A very deadly Founders Day celebration is the backdrop for tonight's Season 1 finale.
Supernatural (9pm, CW) - In other happy-go-lucky finale news, this show's season ends with the Apocalypse.
Fringe (9pm, Fox) - In part one of a two-part season finale, Olivia travels to the alternate universe with Walter, who is preparing for a showdown with William Bell (Leonard Nimoy).
