Need help finding a Monty Python skit

[Pegghead]

As the title suggests, I was wondering if any Python fans knew anything about a particular skit from Flying Circus my father's been searching for lately. According to him, it involved one of the Monty Python crew walking into a phone-booth, which is so grotty and vandalised that he shakes his head and walks out in disgust. The second phonebooth he walks into is slightly less banged-up but still banged-up nonetheless, again making him shake his head and walk out. Finally he walks into a third phonebooth, which is completely clean and intact, to which he smiles, produces a hammer and proceeds to vandalise the hell out of it.

Any help would be appreciated, as after searching high and low through Google, Youtube and Wikipedia I figured asking here would be the smartest option.

Are you sure it was a Monty Python skit? It sounds like it could be but I don't really remember that one. I just looked through the index of "Monty Python All the Words" (it's a collection of the scripts) and I didn't see anything that looked like that skit either.
Sorry I couldn't help you out there. Maybe it's from a different sketch comedy show?

Hmm, I don't recall any skit of such sort and I watched every episode of Flying Circus at the very least twice.
