It's from a really old Nostalgia Critic episode.
Nostalgia Critic is a cynical genius who reviews very old and shitty movies.
In this particular episode, he reviewed the Care Bears movie.
This one line developed into a huge meme, along with a lot of his other trademarks like "Zule motherfucker! Zuuuuuule!" and "A BAT CREDIT CARD?!".
