I think my new obsession right now is evil laughs. I do like subtle and sinister ones but I just ADORE the over-the-top and psychotic ones because they're so awesome, hilarious, and creepy at the same time.

I find the over-the-top ones an overused cliche.

I also like the sinister and subtle ones because it shows that they're calm, cool, collected, in their right state of mind, in control of the situation, and they are using it to cause misery to someone else. Maniacle laughing at least implies that they're off their rocker, thus "not all there," thus you can work around it. A subtle laugh says they're two steps ahead of you and planning the next two.

These are so much more sinister and creepy. I love them.
