Today is the second and last Friday 13th, of the last year 13 for a century, so if you'resuperstitious, Friday 13/12/13 might be a good day to spend in bed, perhaps with a little light YouTube or something similarly harmless.
If you're not superstitious, why not join flight 666 to HEL? Yes, seriously, flight AI666 to Helsinki, Finland, is indeed flying on Friday 13th (and, frankly, Helsinki at this time of year is pretty close to hell).
Better yet, Finnair, unlike some southern European airlines, does have a row 13, with seats available in it. Which means that, as you read this, at least one lucky individual should be flying in row 13, flight 666, on Friday 13th, from Copenhagen straight to HEL - and possibly back.
We're not particularly superstitious in these parts, breaking mirrors and walking under ladders with gay abandon, but if you're staying in tonight, we recommend you join us in a suitably named Black Bison Martini, based on the ever-drinkable Zubrowka bison grass vodka.
