Old Spice after-shave has a new ad running. Some say it's hilarious. Some say it's downright creepy.

Watch "Mom Song" and see if you relate!

The premise of the ad for Old Spice is simple. Boys turn into men, girls become girlfriends (with Old Spice's help, of course) and moms become sad.

The ad has quickly gone viral. Most are fans, and say the commercial is hysterical, but more than a few are creeped out at the thought that moms actually think of their baby boys in this way.
