One of the hottest viral videos out in the last few days is about something that many of us know a thing or two about -- fast food.

We've all been there, saw a beautifully stacked and deliciously full burger on a TV commercial and your mouth begins to water. So you run out to (fill in the blank fast food restaurant) to get said burger and what is placed before you is usually something totally short of your expectations.

Why's this burger so mushed and flat?

Well a guy decided he would go on a mission and see if he could get restaurants to make his burger like it appears on television commercials. The results are pretty amazing.
