An early tradition was to present the guest star with a Muppet likeness of themselves as a parting gift at the end of the show, but this only lasted for the first two episodes produced, featuring Connie Stevens and Juliet Prowse. The high cost and effort of creating these unique Muppets, scheduling conflicts, and potential legal issues contributed to the decline of this practice, although Muppet caricatures and parodies would continue to appear. The practice did however take place for actors Michael Caine and Tim Curry, who were the lead performers in "The Muppet Christmas Carol" and "Muppet Treasure Island", respectively.
