I watch Two and a half men regularly, and i just think, either he is based on someone real, or they the writers just really get off on sex scenarios.
I don't know anyone whose that much of a horny bastard. he has his own website of hate
For a short time when I was in college I had a room-mate that was a psychopath. All he did was sleep, eat, smoke pot and fuck. He had a girlfriend at home and a girlfriend at school and both of the girlfriends knew of the other.
The only reason he could get away with this behavior was because his parents were rich and gave him loads of money.
At the end of the semester he was kicked out of the dorms because he and the people with which he smoked pot had so badly damaged the dorm room.
I know he flunked out of school because he didn't have the intelligence to pass college courses without going to class and studying.
He was just like Charlie Harper except he had neither the intelligence or the talent to pull it off for a lifetime.
