When you think about it, BBC could save a load of money by building 1 city-sized set and putting all their TV shows there. Peter Kay and the other one from that show could be giving a lift to Dr Watson on his way to see Dr Who perform in the QI house, with Chris Evans sitting alongside them and reviewing the car. Matt Baker could appear every now and then and do short pieces to camera, while everyone is doing ballroom dancing.
Sorted.
