Why are people Pirates?

Just because they AAAaargh!

Took a few around town and yet to pick ''it'' when there was a yelp from She who must be obeyed "BRIAN!" I hurtled through in time to see a bunch of Pirates' bums disappearing into the distance.
By a weird coincidence I was in the garden to hear them AAAARGHing their way back, complete with old sea-dog (Well, maybe middle-aged) shot off a couple, then asked them to do a ceremonial Aaargh, just for the camera.

It seems they were advertising this.

BTW Ref:- Yesterday's shot ... The actual date was the 27th, but we were away.
