This funny escalator commercial is a classic, and has been used as an example in some marketing courses. I was reminded of this video by Baekdal.com's article of 7 Viral Marketing Tricks.

I felt it would work better with just a slight rearrangement of the text placement, but I'm picky. Your thoughts?
