My first reaction was 'that is a brilliant idea', then I thought about it and realised that, save the sleeping together, that's actually exactly the plot of the Johnson episode I linked. Hmmm.

(I've seen all the Peep Show episodes aired so far, by the way, so don't worry about spoiling me.)

Jeremy Usborne is a bit like Jeremy Clarkson, in the 'has terrible, terrible ideas and then drags his friends into carrying them out' sense. They should never meet.
