Fawlty Towers: Season 2, Episode 5

2 - 5: The Anniversary

Basil invites some friends for a surprise wedding anniversary party, but Sybil assumes he has forgotten their anniversary and storms off, leaving her husband and Polly, in disguise, desperately telling the others she is 'ill', while Manuel and Terry constantly quarrel over who will make the seafood paella which Basil had permitted Manuel to cook for the occasion.
