Low-cal Blue Cheese

I get so pissed off when I have, like, a cheeseburger and a Diet Coke, and somebody makes a foolish commented like, "That cheeseburger kind of cancels out the Diet Coke."  I want to subtract calories when I fucking can.  Doesn't the fact I take in extra calories with the cheeseburger necessitate the fact that I drink Diet Coke?
