Of all the irritants hardy Edinburgh festival-goers must put up with (in between the 24-hour entertainment on tap and endless parties), the continual assault by chirpy people handing out flyers comes high on the list of sour gripes. Throughout August, pacing the Royal Mile between shows at the Assembly in the New Town and up on the Pleasance is akin to running a particularly wacky and ingratiating gauntlet. But it's not just the crazily face-painted, juggling students in drag on stilts which irk, it's the flyers themselves. Why do comedians choose to advertise themselves with such low-rent, uninformative and frankly unfunny material?
