Tonight's episode, "Granny Annie" per wiki:
Bo and Luke learn that a family friend, seemingly innocent little old lady Granny Annie, is operating a small-time counterfeiting ring. Boss Hogg has Granny Annie arrested and confiscates her engraving plates, and sells them to a no-nonsense mobster for $25,000. Bo and Luke set out to clear Granny Annie's name by stealing the plates back and throwing them into a lake ... unaware that the mobster has found out about the theft, assumes Boss is responsible, and plans to kill him.
Here's what I learned from the Dukes tonight:
Apparently The Oak Ridge Boys' 1979 World Tour included a one-song set at the Boar's Nest bar in Hazzard County.
