Before the 1990s, there was a stretch of time -- roughly 10 years or so -- we refer to as "the '80s." It was, like, this totally rad era in which a geriatric Rodney Dangerfield could be a party animal, coke was a problem and New Coke was an even gnarlier problem. And the only rule for your hair was that it had to appear hilarious to anyone not living in the '80s.

With the jukebox broadway musical "Rock of Ages" coming to theaters, we say it's time to grab a pogo ball and hop our way through the historical hallway of hairstyles, searching for what made '80s yearbooks into the comedy treasure chests they've become.
