In one of the least popular Doctor Who episodes, the good Doctor is entertaining guests. Suddenly, someone points out that he forgot to move his clock back one hour. The Doctor freaks out. His guests try to explain that he only has to adjust his clock by turning the knob at the back. Despite protestations, the Doctor insists on dropping everything and using the TARDIS to travel back in time and fix the problem. Needless to say, Doctor Who gets his way, the problem is dealt with 15 minutes into the show and everyone is left sitting around in silence with nothing to do for the remainder.
