Tony tries to impress Deborah by pretending that he can speak German - His plan backfires, however, when Debs gets a letter from a German customer and asks him to translate it for her! Gary begins to suspect that Tony is gay.

Deborah is ill, so Tony decides to look after her. Meanwhile, Tony decides that his girlfriend is getting too serious for his liking so sets about finding a way of dumping her without having to tell her face to face!

Dorothy demands an explanation when Tony sells one of her LP records, which is a 'rare' collectors' item worth £200, which is green in colour. Gary has to find a replacement! - The replacement LP is black, so Gary tries to paint it green! When Dorothy is not convinced, he has to pay her £200. Then, Tony tells him that there was a misprint in the catalogue - the green LP was only worth a few pounds!!!

Tony's brother has come to stay and so does his girlfriend. Gary ends up wanting to kill both of them. Then he finds out that her parents have a holiday villa which might be available for a free holiday. Now he'll have to be nice to them both!
