Pirates: When will the Fad End

It all started fairly simply. Johnny Depp stars in a movie about pirates, it blows up, now everybody wants to be a pirate. The skull and crossbone logo, once only reserved for anti social high school students is now trendy, gracing bags, binders, caps and clothing. Men are now wearing crazy Jerry Seinfeld-esque puffy shirts. It has even infiltrated facebook...with applications allowing you to recruit pirates for some reason. Is Johnny Depp the only reason that pirates are popular? Are there other factors influencing this? Maybe we just love the idea of swashbuckling and stealing a cool treasure. Or maybe everyone just love a puffy shirt.
