I was out Friday until the early morning and seated next to a halfwit on his first trip to New York City. I suddenly slid back into consciousness when I heard him say, "I mean, I don't care if I hit on ten girls if one of them gives me their number. I don't even care if we break up after a few months unless she's super hot." His drunken blabber sparked an epiphany. I said to him, "Because you have a sperm mentality." His brow furrowed and I explained. "I'm selective about who I even like, and if we break up, (and I'm not the breaker) it's a big deal. Biologically I have a limited number of eggs and my biological clock is ticking - in a parellel way I take dating relatively seriously. You on the other hand, have invested almost nothing and your sperm is nearly exponential." He stared at me blankly and smiling slowly said, "Exactly."
