After taking Magda's advice to rub vodka on his cut eye - which makes it more painful - Rick agrees to sponsor Michael's charity skipping marathon but realises that,due to a misunderstanding,he will owe him five grand and not a fiver. His offer of a five hundred pound flat rate is refused so Rick has to take drastic action - 'accidentally' running Michael over, and getting arrested as a result.
