A Hard-Drinking Party Girl can double as the Lovable Sex Maniac with, interestingly, very little change just because she's female. Bob is in love with Alice, but Alice not only fails to realize it, but is already in a relationship with Chris.
It went on to become a major hit, selling 557,430 copies in its first week and almost a million copies by the end of its chart run.
In the real world, of course, such behavior will land you in hot water — but on TV, the worst you'll get is a whack from a Hyperspace Mallet.
The only thing that keeps the Lovable Sex Maniac from being a truly disturbing Anti-Hero is that his antics are always played for laughs — and the odd thing is, it usually works. Compare to the Extreme Omnisexual, who is willing to sleep with anything, but might not have sex on the brain all the time.
Sometimes, somehow, Bob gets the idea that Chris is the one in the way of Bob's happiness with Alice, and if Chris were to somehow have an "accident", then surely Alice would come to love Bob instead.
It's true — Love Makes You Evil and these characters are Not Good with Rejection. Sometimes, Bob may not even consider what would happen if Alice ever found out.
