Fawlty Towers

Based on an actual hotel Cleese and the MP gang stayed at once, Fawlty Towers is a hilarious British sitcom with great characters and situations. Probably the most famous episode is the one with the Germans, as I hear it referred to the most.

Basil Fawlty (Cleese) is a grumpy hotel manager, with his domineering wife Sybil, the hotel maid Polly (co-creator and Cleese's wife at the time of the show Connie Booth), the Spanish waiter Manuel ("I learned classical Spanish, not this strange dialect he's using"), and the hotel's longest standing resident, the Major. Witty dialogue and hilarious slapstick situations make this a great show.
