There will always be something a bit surreal about seeing images of actual humans with their hands stuffed inside familiar faces like Kermit, Miss Piggy, Fozzie, and Gonzo — not to mention a man sporting Big Bird’s legs like casual trousers. As A.V. Club pointed out over the weekend, many behind-the-scenes photos taken from the early days of Sesame Street have been making the rounds online lately. Here are some more photos from The Muppet Show, Sesame Street, Fraggle Rock, and even a couple of Muppet movies, courtesy of Muppet Wiki. And no, we didn’t forget about Emmet Otter’s Jug-Band Christmas. Check out the gallery after the jump.
