I think Harold picked basically the "hottie"- the central type of person that everybody would have picked. She was drop dead gorgeous... but turning it into a long term commitment relationship that could potentially lead to marriage, hahaha! That's a laugh and a half because, as long as he's in his mid to late 40s, approaching 50 and he keeps picking 25 year olds, he will be single and alone for the rest of his life.
As far as Dave goes, Dave is a "Peter Pan." He is a guy that just doesn't want to grow up. He's impressed with himself as far as image goes, but he wouldn't be in the Sex Toy business if he wanted to be a banker or lawyer conservative type and get married and settle down. The fact that he says to me "I want to get married and have kids," is ridiculous. With a striper pole in the middle of his house, and his furniture set out for party central, his life revolves around a "good time". It's no wonder that he attracts what he attracts. I think it was great that Brooke gave him a chance being a "Harvard Hottie" herself, but time will tell on this one because I don't think that Dave has the wherewithal to hold onto a relationship, as he hasn't had many relationships to begin with.
