Kermit’s doctor played by Linda Lavin (TV’s Alice) diagnoses him with Amnesia
from Muppets Take Manhattan (1984)
KERMIT’S DOCTOR: “No doubt about it, you have amnesia. Now, the problem is, you were found with no identification and oddly enough, wearing no clothing, so I did some research into the major nudist colonies in the area and I think I’ve come up with something…”
KERMIT: “…oh?”
KERMIT’S DOCTOR: “You are Mr. Enrico Tortellini of Passaic, New Jersey”
KERMIT: “well…I really don’t feel Italian.”
KERMIT’S DOCTOR: “…it was just a long shot anyway”
