[Phil], Secret Santas are agents of the devil. It's OK to impale them, or just any random person if you can't work out who bought you that pair of yellow socks.
The only problem is all these lunches take time that I don't have. They break my thinking when I could be usefully engaged writing webpages or brochures or news ot other stuff. Luckily it was back to just half an hour today. OOoh yellow socks filled with coal! Great idea!
