Aunt Bea’s pickles - one of the greatest sitcom episodes of all time!!!!!
Two other great ones:
WKRP in Cincinnati: “as God as my witness, I thought turkeys could fly!!!”
Mary Tyler Moore: the funeral of Chuckles the Clown
Not a sitcom, but Carol Burnette show: Tim Conway’s ad lib bit on Saimese elephants
Tim Conway was a genius…
