Along with Jonathan Calder and many others, I am a great fan of the Guardian's Corrections and Clarifications column.
It's a thing you need time to read and appreciate, as the hilarity of some of the items is not apparent without a few seconds reflection.
Take this correction from today's Guardian:
"We printed the wrong Lotto numbers in yesterday's paper (Page 9). The winning numbers in Wednesday's draw were 2,5,15,34,35,43, bonus 12."
Somewhere there is some poor Guardian-reading, Lotto-playing soul, who now has an overdraft of about £2,000 spent on champagne and "triples all round", plus cancellation fees for a dream holiday and, perhaps, a large element of humble pie to eat in front of their boss.
