I was 100% sure it was Mitchell and Webb, before I went looking for it and couldn't find it.
Some people are standing around in a futuristic setting, making chit-chat, but all their conversation is punctuated by random utterances of things like "hail zoltan" and "by zoltans glorious beard". (Example utterances only. Not sure if the name was actually zoltan). At some point, one character pipes up with " why are you all saying 'hail zoltan'? It just seems like I was away sick on Wednesday and when I came back everyone was doing this zoltan thing". And then everyone passes the buck in a "i dunno. I started doing it because Joe was doing it" fashion. Help, please?
