S6·E1 Jed Inherits a Castle

Jed gets a letter in the mail saying he has inherited a castle in England. Jethro reads up on England & Queen Elizabeth the first. He thinks that England hasn't changed in 400 years & Knights still fight dragons. The Clampetts go down to the passport office to apply for their passports & the Clerk thinks he's on 'Candid Camera' & they're actors trying to fool him.
