Do you know what a snarf is? It's kind of when you laugh and snort at the same time. I "snarfed" when I watched this ad. It's a good thing I didn't have a mouthful of Diet Pepsi or something or I would have drowned myself.

So this is apparently about a "hands free" cell phone.  It makes a good point that there are a. somethings you can't do when you're hands are full and b. somethings you don't want to do when your hands are full.
