Sybil thinks Basil has forgotten their 15th wedding anniversary. Actually he has arranged for some friends to come round and for Manuel to cook a special paella and there is to be champagne. Whilst cook Terry is berating Basil for not letting him cook the paella, Sybil drives off in a huff. Not wanting to confess this to their guests, Basil pretends Sybil is ill. However they insist on going up to see Sybil and Polly has to don a wig and pretend to be Sybil. As found in the collection, FAWLTY TOWERS.
