Royals finally get the point.
The traditionally working-class pastime is becoming a firm favourite among our beloved Royals.
Last year, Prince Harry turned up at the PDC World Darts final. This year, it was Zara Phillips, who surely grew up in a house where the only darts in use were the "sleepy" ones they had to fire at Otto the pony when he was being a little boisterous.
She was accompanied by husband Mike Tindall, who looked a little intimidated. Well, I suppose the Ally Pally crowd does seem quite posh after an autumn spent watching dwarf wrestling in the colonies.
Darts fans will, of course, welcome this new breed of spectator with open arms - and not just to get those Latin tattoos on their biceps translated.
They will see this Royal stamp of approval as a milestone in their sport's journey to mainstream acceptance. But they should be careful what they wish for. Football crowds used to look and feel more like darts crowds, until they were similarly gentrified.
Enjoy your moment, darts fans, but don't come running to me when prawn sandwiches replace pork scratchings, and the chap beside you thinks an "arrow" is a public school in Middlesex.
