It’s as much fun as you’re going to have in a movie theater this year.
Look up at this commercial. Look down at the interview about how they made it. Anything is possible when your man smells like Old Spice and not a lady. And if you're really going to put that message across, you have to respect the integrity of the frame-space. This hilarious bit is accomplished in one shot (requiring three days and quite a few takes), with only one obvious use of CGI (the appearance of the product itself) and one invisible use (erasing a piece of equipment from the shot at the end).
Buster Keaton would approve -- though he probably would have found a way to do everything in-camera.
