Recently saw an episode of Quantum Leap and decided to take a stab at the effect while I was sitting around one day...

Didn't take the time for good masks or anything, so really rough...

A little nod to Mel Brooks as well...

Edit: Thanks to everyone that commented on the vid! I feel I need to address the major complaint that I don't say "Oh boy.." at the end. I actually do say it (how could I not!?), but when I composited the head onto the body, the hoodie was blocking the mouth. Initially this was just a quick and dirty play-around test, so I didn't bother messing with it anymore (what can I say, I'm lazy and didn't want to re-shoot that part). I certainly didn't think it would get thousands of views (but ain't that a kick in the pants!)

So I assure everyone that "Oh boy" is indeed said at the end, it's just that the mouth is blocked by the hood. If I could go back, I'd wear a tshirt or something...so there's your lesson kids! Consider your wardrobe when making effects tests!
