Can't Even Believe the BBC

Just watched the BBC's Bargain Hunt programme. Two contestants were given the challenge of buying an 'educational item'. A plaster model was purchased. This was described (by experts, contestants and auctioneers) as a model of the human gut (gastrointestinal tract). It was very clearly a model of a kidney nephron with the Bowman's capsule. It seems extraordinary that nobody ever corrected them. A gut and a nephron are nothing like eachother (except being tubular), they are on different scales and serve entirely different purposes! Not much education there!
