OK Brad, you wanted Tales of the Fanboy, I've got one. ( I really wish I didn't!)
I dated a guy in college for 2 years that was a total fanboy. I have way too many stories to tell here. I told him up front that I didn't like Star Trek, and that was a love he was just going to have to indulge in when I wasn't around. Well, the problem here is, he has a chemical imbalance, and his moods fluctuated wildly all the time. He was on and off antidepressants most of the time we were dating. This wouldn't be so bad, except he knew he could use this to manipulate me into doing whatever he wanted. If Star Trek was coming on, and I told him I didn't want to watch it, he would pout and mope and generally be pitiful until I caved. I even went and saw First Contact with him in the theaters! He basically used this ploy to get me to do whatever he wanted. And he would spend any money he had on Star Trek/Star Wars toys, while we were going out on dates dutch! We were engaged for a while, and he couldn't afford to buy me a ring, so I he gave me a twist tie from a loaf of bread as a ring, and I wore that thing around as proud as if it was a 5K diamond! Then he got this great internship where he saved up a lot of money and I thought "Finally, he's going to buy me a ring!" No, he bought himself a Mac, a SECOND TV for his dorm room, lots of movies and Star Trek/Star Wars toys! And couldn't understand why I was so hurt...
He used to tell me all the time that I was in the wrong major, that he knew more about computers than I did. He was an art major and had a ton of free time. I was computer science and math and had homework every night. He would tell me that I was stupid and then would sabatage my study time. I mentioned he had a Mac, well he bought computer games that could only be played on a PC and then would call me when I was trying to study for a big test and tell me he wanted to come over and play his games. When I would say No, we went back to the whining and begging and moping until he got what he wanted. If I tried to block him out while he played, he would turn up the speakers and talk to me every couple of minutes, and then when I would end up flunking the test, he'd say "See, I told you, you're too stupid to work on computers."
The final straw was my 21st birthday. It was on winter break, so he drove to my home to spend the day with me. It was a 2 hour drive, but the way he talked about it you'd have thought it was a big deal! We spent my birthday at Wal-Mart, with me buying him a Star Wars toy that he didn't have the money for. Lunch at Burger King, which I paid for. Then my sister had a great surprise for me. She wanted to get me a cat for my birthday. but she wanted me to pick it out. I thought this was great, so me, my sister and my boyfriend got into her car and went to the shelter. Well, that near to Christmas the shelter doesn't want to give out pets, so we went to several pet stores, all out of cats. We drove out of town and finally found one. The whole time my boyfriend is in the back seat grousing about how he came "all this way" to spend time with me, not look for a cat. So, we go in, and I see this one cute kitten. But she didn't look really healthy, she had a weepy eye and was really tiny. My sister tried to convince me to pick another cat, and I handed the kitten off to my boyfriend to look at another one. It was at that time the sick kitty took a big diahhrea dump all over my boyfriend! All down his coat, his shirt sleeve, his jeans, his shoes and into a big puddle into the floor! My sister then exclaimed "That's the right cat for you!" and she came home with us.

Once I got that little ball of love home, I realized that she showed me more unconditional love than my boyfriend ever had. So I dumped him. I still have the cat, though she loves on my husband more than me. She always could tell a good man from a lousy one!
