No luck...
Its on several sites that post clips, including Google, TV mania and quite a few others. Looks like it was first put out about five months ago and then proliferated all over the place after that.
Several comments implied it was an 'old' clip, but nobody stated from what show. Other comments labelled it as 'Python-like' material, but Im a big fan of the MP group and have never seen this before.
If anyone else can help, I would still like to know.
