The Academy of Fine Arts in Bologna is hosting a 3-day festival that will celebrate and explore the human propensity to screw up. They're calling it Error Day. Festivities begin on Feb. 28 and continue until Mar. 2.
From the website for the event
(which is mostly in Italian, but has a few pages in English): "Welcome errors, blunders, mistakes, miscarriages, misunderstandings, omissions, faults, failures, inaccuracies, misapprehensions, oversights, misprints, howlers, wrongs, gaffes, lapsuses, goofs, betrayals, fails, falls: here is humanity's true common denominator!"
