The lesson for being big?
Each of our protagonist's wishes was supposed to teach him a lesson, right? If you're really sensitive, it can work against you. If you have lots of power, you also have lots of enemies. And so forth.
But I kind of missed the point of the lesson when he wished to be a big tall strong sports guy. I thought they were going to play on him being really dumb, but it actually boiled down to him having a really small penis. Was that really the right way to go? What lesson was that supposed to teach our protagonist?
I mean, is this the message: being big and tall is the right and only way to win over a woman, regardless how dumb you are or anything? Size matters?
