Do you remember the Fungo Brothers? That mismatched sibling duo who were hellbent on creating bold, innovative workout techniques that were years ahead of their time? You know them! They invented the Thigh Master before it was, well, the Thigh Master. Not ringing a bell? That's okay, Dwayne "The Rock" Johnson and Jimmy Fallon are here to help.

Johnson ("Mr. The Rock"?) spent some time on 'The Tonight Show' last night to chat up his latest big screen outing -- this week's opener, 'Hercules' -- and, of course, he had to share some workout tips with Fallon. Turns out, these crazy kids were into the same exercise tapes when they were younger. Really, you don't remember the Fungo Brothers? They sure look familiar...

'Hercules' opens this Friday.
