HOT LESBIAN ACTION!!!

Love. 15. 30. 40. Game. I'm pretty sure everyone knows what I'm talking about. But for those of you who don't, that's how they score a game in tennis. I read somewhere that the reason 0 is called love is because in the old days of tennis before the U.S. exsisted, they called 0 l'oeuf in France, which literally translates into "the egg". Now I mean and egg representing 0, I can deal with that, that makes enough sense. But if you win the first point, you get 15 points. Then you get 30 points and then 40. It doesn't even make sense. Why do the first two points increase your score by 15 each time, then you get 10 points and I think when you win the game you have 50 points. How hard would it be to just say, 0,1,2,3,4 and you win. People who watch tennis often have gotten used to the way they score it. I have gotten used to it a while ago, but I think it's really stupid. If anybody knows why they score it this way, tell me. All I'm asking for is a simple explanation. Later much fanatics, I'll see ya around.
