Couldn't resist this.

"Dear Sir,
How refreshing to see a column (David Aaronovitch "The Observer" Sunday May 9th) where the writer is able to avoid the situation in Iraq, and cheer us all up with a witty and highly relevant article about the last episode of "Friends" the feelgood American TV sitcom. There is too much bad news these days! Well done David.
Yours faithfully,
Stephen Wills."
