Dear John: what the hell is that? Travolta's brutal butch hair -- or lack thereof, handlebar moustache aside -- in this week's remake of The Taking of Pelham 123 got us nostalgic for ol' dimple chin's former career of chaotic coiffure. From those grease-slick quiffs of his jive-talkin' daze through the '80s aerobic mullets, '90s hitman mops and one almighty intergalactic octopus that took up residence on his skull in the dying embers of the millennium, the state of Travolta's pate has never been less than eclectic. And so we present a best and worst gallery -- how could it be anything else with this guy? -- to salute Travolta's tonsorial tenacity in contributing some of movies' most hair-raising moments.
