Guys . . . have you ever dated a TOTAL PSYCHO? Of course you have. Who hasn't?

But you know what the sickest part of it all is? You probably KNEW the girl was crazy from the start, and you still went ahead and dated her anyway. So why would you do such a thing?

Here are five reasons why guys go for crazy chicks, according to Glamour magazine:

\#1.) Guys want to be heroes: Men love to "fix" stuff, and they love coming to the aid of a "damsel in distress." Truthfully, they can't help it. It's hardwired into the male DNA.

\#2.) Guys figure she's probably crazy in bed, too: Here's how the logic goes: men figure that if a woman is crazy in her day-to-day life, then she's probably an animal in the sack as well. It's not necessarily true, but it's worth the gamble.

\#3.) A lot of guys have "mommy" issues: Never underestimate how much a dysfunctional mother can screw up her kids. Never. It creates guys who can't help but WANT to be around crazy broads . . . because it's all they've ever known.

\#4.) It makes guys feel better about themselves: When your girlfriend is more screwed up than you are, it makes your own problems seem minor in comparison, and much more manageable.

\#5.) Some guys don't want anything serious: If a guy isn't ready for real intimacy and commitment, then it makes sense to date someone who's so balls-crazy that he couldn't POSSIBLY fall for them.
