There is (as there is in most versions of the Arthurian legend) a nice scene near the beginning of Excalibur where the Knights all gather, full of determination to yank the sword from the stone before giving up, sadly disappointed. Having bought a huge jar of Dill pickles that I am unable to pass by all day without taking yet another unsuccessful crack at trying to open the jar, I know just how those knights of old feel.

WAH!! My pickles are trapped forever :(
