Beer Bottle Dominos

Someday, I just knew somebody would take a bunch of empty beer bottles and pencils and set-up a huge domino effect in their house. I've dreamed about it, and common sense says it's just inevitable.

Now that it's finally been done, this video poses a lot of questions for me (but you have to watch it until the end for the classic payoff).

1. Why?
2. How freakin' long did it take to set this up?
3. Why?
4. How many takes?
5. Why?
6. Is this the greatest accomplishment in the history of mankind?
