Why: The first season of The Muppet Show
What: Miss Piggy made a brief appearance in the premiere as half of a dancing couple (presumably before she got some vocal coaching, as she sounded like a cross between Mrs. Doubtfire and Margaret Thatcher). But she truly made a splash at the top of the second episode by socking Kermit in the jaw. It’s so strange now to see her before she was a superstar – before the first eye job, the first snoutoplasty, the first anti-frizz and hair dyes. Just a simple country pig in an evening gown, trying to punch a frog, like nature intended.
