Homeworking jokes

How many homeworkers does it take to change a lightbulb?

There seeems to be a real dearth of homeworker and shedworker jokes in the world. In fact to be honest, I've never heard a single one. So if you have any - reasonably clean - ones, please do let me know and I'll put them up on the site and also include them in a future issue of The Shed.
