I think the course writer's use of absurd is to shock us into remembering the structure rather than the vocabulary. It is a typical "cadavre exquis". Admittedly the DK course has rather a lot of them! I don't find it a problem, what bothers me more is the poor English written by non-natives that never gets corrected.
