I don't have to make ideas just on the fan fiction section.
Here's the part of the first episode of this new Muppet show:
KERMIT: "OK, what's next for today?"
(Harry the Hipster from Sam & Friends appears.)
HARRY: "What can I do fer you?"
KERMIT: "I'm waiting for another contestant."
HARRY: "Hey, Kermit ol' pal! it's been about 20 years since I saw you. How can I interest you a song?"
KERMIT: "I'd love to hear your song, Harry."
HARRY: "Ha-ha! You'll love this one, I will sing this song by Diana Ross.
KERMIT: "OK. Let's hear it."
HARRY: "OK! Hit it!"
("You Can't Hurry Love" by Diana Ross plays, then Harry then sings it.)
What do you think?
Perhaps the performers would decide, if Harry the Hipster would be the winner.
