It's April Fools' Day and head office has insisted the occasion be marked by morale-boosting practical jokes. The smokers are not amused.

It's April Fool's Day and despite Sharon's protestations, Head Office have given instructions that the occasion should be marked with suitable practical jokes to boost staff morale.

Janet has been issued with a box of 'amusing' props to distribute around the building, but the smokers are having none of it - for once, most of them share Sharon's viewpoint on this pointless enterprise.

Talk instead turns to the cruel jokes life plays on you, and the general mood isn't improved when Clint arrives, uncharacteristically down at heart and stubbornly refusing to share the source of his woes with his friends.
