What's the worst thing you've ever done?

Sounds like a great couple-three top ten lists to me, but for our purposes today, we are going to concentrate on the "time-value of money" category.

During a short period of self-reflection, I today, realized the worst investment of any increment of money, ever imaginable. I'd like to convey what a serious and deep statement I am making. The person making this statement has commited the following sins against personal finance:

A) Spent my last $14 buying a Don Mattingly poster on a trip to Yankee Stadium in 1987. This was my first trip to NYC. I was eight. I remember two seperate times not being bored on this tourist trip with my Mom and Doug. First, Doug took me to an Irish bar during daylight hours. Too many beautiful concepts at work to discuss further. The other was after my first game visitng "The House That Ruth Built". This happened the night before I flew home by myself. FYI, the Yanks were not the complete Evil Empire they and the Red Sox are today. This poster was the greatest way I could have spent $14 I'd ever thought possible. I was gonna go home and show all my friends I have a Don Mattingly souvineer from Yankee Stadium. I left my poster on the plane.

B) Refused to consistantly check the oil on my Blazer. This car was a friend's and he practically gave it to me after he graduated college. The only problem with the car was a small oil leak. I needed to check the oil once a month and put more in. This was a task way too complicated for me. I left the car on I-4.

C) I bet real money on the Washington Generals. "They were due to win one!"

Also keep in mind the endless amount of cash I flushed down the port-o-potty in college - all the withdrawals, failed classes and the ones I just stopped going to. All of these are better ways to throw away money than in 1989, I spent $3.75 to see John Travolta and Kirsty Alley in Look Who's Talking. I don't know who I am more angry with; Myself for being this stupid or John Travolta for shitting on my money. Let's just say Mr. Wonderful received a 5% cut of my $3.75 - That would be worth about a dollar now. You have any idea what I could do with a dollar now? I could buy a song on iTunes. Or about 5 songs from this Russian website.

You could say I spent about $16 in today's money, with the time value of money theory involved. For the record, there is no time value of money equation in the Don Mattingly poster because that was pricess to me at the time. There was no dollar value on the loss of the car, because I got the next one I ruined for practically nothing as well (they were both shitty cars. Free, but Shitty). And, I didn't really bet on the Washington Generals, but Krusty the Clown did and we know how that turned out.

Myself and the other four hundred, sixty-three people that paid acutal cash money to see Look Who's Talking ... okay, and Look Who's Talking Too - Hey! We had to see how it turned out, have now commited the ultimate sin. We've helped create the Scientology monster. We've helped perpetuate a group of people that give more creedence to a group of rogue aliens starting life on Earth than to a Supreme Being. This is a group of people that has reset the bar for crazy. They are the most out-there group. No one can top them. Not Britney. Not the guy who sells flowers in a straight bar with no chicks. Not the guy who rides his bike all over town and belts out the National Anthem to start Little League games. No one. You're move, Christian Coalition.

I challenge you America (at least the seven of you that know about the blog): What was the WORST personal finance crime you've committed ? Discuss.
