Jailhouse Rock Elvis is our favorite version of the King of Rock 'n' Roll.
Did you see the 1957 movie? Legend goes that Elvis is the unofficial choreographer for the jailhouse scene. The hired choreographer wanted a more classical dance number to accompany the song, but asked Elvis for input. When Elvis broke out in his iconic jelly-leg dance moves, it was decided right then to put that image on a pair of men's dress socks (just kidding).
