Re: Assignment: Earth - Is it Really a Star Trek Episode?
All I know is I love a young Teri Garr.
A young Teri is in two episodes of It Takes a Thief
from 1969 if you can find them-- as Maggie Philbin in both "Guess Who's Coming to Rio" and "The Beautiful People", though she's billed under her given name of Terry.
Rejoice, brethren! Soon we shall be walking in a winter wonderland.
