As I recall when Challenge showed the snake charmer episode of Catchphrase, in later airings I'm pretty sure they edited out Mr Chips' walking stick or at least did something to it which spoils the whole moment on the repeats and anyone young and new to the episode wouldn't understand the laughter.

Yeah, the censored version doesn't have the animation of Mr Chips' arm but it's still funny because of the winking.
