Alex McLoughlin might be sweeping you off your feet as Hawaii Five-0's Steve McGarrett, but no amount of charm will ever replace Jack Lord and his sweet 70's combover.

The popular Hawaii-based police drama is currently in its fourth season, but the original show -- which used the letter "O" instead of the number "0" -- was a television classic that blessed TV sets across America for 12 wonderful seasons. Enjoy a blast from the past with these vintage Hawaii Five-O snapshots.

Book 'em, Danno!
