Screw that! Go for the <b>double</b> Quarter-Pounder w/ Cheese (or Half-Pounder, more precisely). I gained 40 pounds in college on that diet.
I've been shorting McDonald's for a couple of month's. Was just a hunch when I saw their "value menu" commercials. What a joke! I've been pretty accurate, so far. Just seems like the Company has lost it's vision.
And their market share. McDonalds sales have been declining for the past 12 straight months. That is the first decline in their sales in a LONG, LONG time.
