Dick for Tat - S5.E2

When a drunk Mary tells Dick she once had a fling with his archenemy Vincent Strudwick, he is outraged and decides to get even with the pair of them by convincing Strudwick's wife to sleep with him. Tommy supports Dick's decision, imagining double dates - himself with Alissa and Dick with Strudwick's wife. Meanwhile, Sally gets the hots for Don after he starts riding a police motorbike, but the pair crash and Don ends up in full body plaster.
