You, Happier, I guess?

So Best Buy just ran an ad with the trademarked tag: You, Happier.

Now there seems to be alot wrong with this sentence. At first, I wasn't sure if this was a comma splice because I'm not sure if You or Happier can be a sentence on its own. If they can't stand alone then I guess it's not a comma splice because it's already grammatically incorrect.

But even if it ISN'T a comma splice, why is Happier capitalized? They would have been much better off leaving off punctuation all together.
