Why, you ask? More candy would be more fun, not less candy, you say. Well, you're right, in a sense. But the term "Fun Size" isn't supposed to be the amount of what you eat.
It's not how big it is, it's how you use it (not that I even need to use that excuse).
You see, these "Fun Size" candy bars are for THROWING. If you get one, you chuck it at one of your friends faces, give them a bloody nose, and start laughing hysterically. Then they're thinking what an idiot you are for giving them candy. But... to their dismay, it's only a "Fun Size" candy, bummer.
If you were to throw a normal candy at your friend's face, or... dare I say "King Size," then they would be getting the better end of the deal. Candy can cause only so much damage, after all, so a "King Size" might not even make much more damage then a "Fun Size" candy would.
Think of it this way, for 5 bucks you can get what, 100 "Fun Size" candy bars? Or, for the same amount of money, you can get maybe 5 "King Size" candy bars. When you look at it this way, the "Fun Size" candy looks much more fun, as you can get more PPD (Pain Per Dollar).
So, in conclusion, "Fun Size" candy bars, are, in fact, more fun than those other, more expensive and inefficient candy bars. They are cheaper, more aerodynamic, leave your friends with little compensation, and you can fit more in your pocket to maximize your PPP (Portable Pain Potential).
