I was once discussing this subject with a friend of mine, and took the position that "no one could possibly know why dolphins bone." She grabbed my arm all stared at me all dramatic and said "No. They have sex in eachother's blowholes." I have since repeated this statement many thousands of times.
Also, I'm pretty sure that "fuck bitches, get money" traditionally means "I don't care about women, I care about money" NOT "have sex with women, get money." Anyhow, the former is the sense in which I mean it here. The dolphin, of course, is an anti-hero, which any non-feminist character must be.
