Image description: a screenshot from the Wikipedia page for the Doctor Who TV series, with a user-added caption that reads "Preserve the media you can before it's gone forever." The Wikipedia article reads, "No 1960s episodes exist on their original videotapes (all surviving prints being film transfers), though some were transferred to film for editing before transmission and exist in their broadcast form. [88] Some episodes have been returned to the BBC from the archives of other countries that bought prints for broadcast or by private individuals who acquired them by various means. Early colour videotape recordings made off-air by fans have also been retrieved, as well as excerpts filmed from the television screen onto 8 mm cine film and clips that were shown on other programmes. Audio versions of all lost episodes exist from home viewers who made tape recordings of the show. Short clips from every story with the exception of Marco Polo (1964), "Mission to the Unknown" (1965) and The Massacre (1966) also exist."
The context being that Chang is a freak that doesn't understand being a regular human, and Pierce is politically incorrect because he's a fossil of a human. They're both immediately challenged for wearing blackface by the group.
I agree on the count of Chang, but not Pierce. The group allowed him to use his "shwami" act as part of a plot-crucial heist while taking Greendale back from Chang's army. And besides, I've heard rumours that Chevy Chase really was like that offstage too. Apparently the rest of the cast hated him.
A lot of people have come out of the woodwork saying they hate Chevy Chase over the years.
The group didn't allow him to use his "notoriously awful Swami impression". Pierce did it because he's a narcissist and thought he knew the best way to fool General Chang.
