S06E11 - Look (Stop Me If You've Heard This One) But There Were These Two Fellers
In this episode, Tara is kidnapped by a gang of retired comedians. At first she is tied to a chair and detective-gagged with a white cloth. It is one of the best OTM gags I have ever seen on TV. Than she is taken away and imprisoned in a furnace to be burnt in half. Mr. Steed comes to rescue her, of course.
