Apparently this was in an email that's been doing the rounds:
If you had purchased £1,000 of Northern Rock shares one year ago, the investment would now be worth £4.95. With HBOS, earlier this week your £1,000 would have been worth £16.50. The same amount invested in XL Leisure would now be worth less than £5, but if you bought £1,000 worth of Tennents Lager one year ago, drank it all, then took the empty cans to an aluminium recycling plant, you would get £214.
See the article where I read this, here:
