Supernatural Season 5 Episode 8: Changing Channels

In one fell swoop, Supernatural managed to combine a humorous episode with one that advances the season-long Mega-Apocalypse storyline.  Trapped in a Trickster’s paradise which conveniently resembles (thinly veiled parodies of) television shows, the Winchester boys discover the identity of this candy-loving Trickster and just how large a role he plays in the war between angels, demons, and humanity. 

Things open up “before a live studio audience” and Sammy and Dean mugging the camera on a sitcom-esque set.  And for the first time ever, Supernatural has a theme song with awesomely cheesy lyrics and opening credits that feel like a cross between Perfect Strangers and Family Matters.
