From what I've seen of "The Muppet Show", the best guest stars know how to play along. You can tell that Kris Kristofferson found it an awkward gig . . . on the other hand, Paul Simon (total non-actor) uses his seriousness as a musician while offering the occasional eye-roll at the hijinks. It works.
But Mark Hamill seems genuinely happy to be there, hamming it up at every turn and going all-in with the musical numbers. This episode aired three months ahead of "The Empire Strikes Back", so it's hard to dismiss his appearance as publicity-related. But there he is, beaming like he's just now made it on prime-time. That look of joy speaks volumes. And seeing Miss Piggy dressed as Princess Leia is one of the best images I've ever seen.
God, this was such a good show.
9/10
