Back when I was single, a friend of mine who I work with (we're both married now) was scandalous. I was a "quality" guy whereas he was a "quantity" guy. If 3am rolled around and all that was left in the bar was the 45 year old who wouldn't remove the Marlborough from her lips when she spoke, he'd be leaving with that girl.
One night he told me his strategy: Post a picture of yourself on all the dating sites with your shirt off. Go for the cheesiest, tackyest picture you can muster. That gets all the respectable girls out of the way. Then all you're left with are the skanks. And he was cheap too, so his first date was always cooking for them. He'd buy cheap Kroger meat and do a virtually zero-cost first date. If they put-out, they'd become a door-knocker. Otherwise, he'd never call them again.
And the funny part? He wound-up marring a very attractive former playboy model. And although she was almost as old as he was, she's also in incredible shape -- I'd say extremely well preserved. She's sweet, very attractive and a truly kind person. I almost fell out of my chair when he said he was engaged. I hadn't even met her. But I don't blame him. Opportunity knocked and he answered, so good for him.
