Letters special This is a one off. A Friday special, prompted by a couple of delightful examples of how one can use Google's contextualised advertising to brighten one's day.

Regular readers will remember the rumour causing panic in Lagos, spiritual (and fiscal) home of 419 scams, that picking up the phone is potentially fatal.
