The Futon Critic are counting down the the 50 best episodes of 2009:
33. "supernatural: the real ghostbusters" (the cw)
(originally aired: november 12, 2009)
Just when you think "Supernatural" has run out of ways to poke fun of itself, here comes an episode in which Sam and Dean literally attend a "Supernatural" fan convention. Between its panel names ("Frightened Little Boy to Secret Life of Dean," "Homoerotic Subtext of Supernatural") to its LARPing attendees ("Buddy, I have heard that line 17 times tonight, okay?" notes one of the hired actors. "And all from dudes wearing MacGyver jackets. But you seem different."), "The Real Ghostbusters" took it to another level. And yet once again, the silly gave way to the serious as a pair of particularly invested LARPers remind Sam and Dean how, despite their painfully difficult struggles, it really must be cool to be them.
