Muppet-mania is at full-force with the release of The Muppets tomorrow, and in honor of our felt friends, why not take a moment to remember the perfectly sweet opening moments of The Muppet Movie, which feature Kermit singing his iconic song, “Rainbow Connection?” The nostalgia overload might be enough to make you misty-eyed.

And if you like your Muppet clips more mature, check out one of my favorite viral videos of all time after the jump: a genius mashup of The Muppets Take Manhattan and Manhattan.
