Tiptoe Through the Penfolds - S5-E3
Continuity mistake: Although Danger Mouse is supposed to be on his own, when he turns a corner in the car, in the overhead shot, you can see Penfold sat next to him.
Revealing mistake: When Bill is pushed out of the helicopter and Ralph rescues him in mid-air, its obvious in some shots that it is two sky-divers dressed as Ralph and Bill. Firstly you can see the parachute back-pack bulges on both men. Also the wind is blowing up on Ralph even though he isn't meant to be descending.
