Good guy: I can't get a girl because I'm too nice.
Answer: Maybe it's because you're searching for whores instead of nice girls. The truth is that good boys only finish last because they are too distracted trying to get a whore with a degree, rather than the nice girl everybody calls a nerd/geek.

Good girl: Why don't boys like good girls.

Answer: It's basically the same thing the good boy goes through, but instead the good girl usually lowers her standards in order to get with something she's been trying to completely avoid "BAD BOY". You see, the good girl wants a THUG with a DEGREE, which isn't going to happen!
