The Monty Python sketch referred to by Christian in Syracuse aeons ago (above somewhere) was the bed shop sketch. Mr Verity (John Cleese I think) is a salesman in a bed shop. Every time anyone says 'mattress' to him he puts a paper bag over his head and the rest of the staff have to stand in a tea chest and sing 'Jerusalem'

See Buying a Bed

On a slightly different note, I (little me) wrote a third verse to Blake's Jerusalem many years ago and I'd like it to be sung - if it's any good.

And shall the joy be thus confined;
Cease at the bounds of England's shore?
Shall minds be closed and hearts unmoved
While mute starvation pleads for more?
This must not be - we shall fight on;
Our love extend - our greed destroy.
Then truly shall Jerusalem
The whole world o'er shout out her joy!

What do people think?
