On a scale of 1 to 10?
In the Deep-Voiced “Mwaa-ha-ha-ha-ha-haaaa” category: I’d give myself a 7
In the Whispery-Lorre “Eh heh heh” category: Barely a 5
Haven’t practiced any other categories.
17 years of teaching high school has honed my maniacal laughter to a fine edge. I can have sophomores weeping and wetting themselves in 3.2 seconds. 
Scores: 10.0, 10.0, 6.4 (from the French judge), 10.0, 10.0
The evil snicker is a more refined laugh. I usually score in the mid-eights with that one.
My husband’s evil laugh is the de-caff, diet cherry coke of evil and his evil snicker is even weaker than tepid Tab.
My cackle rates at 8.753 and my bemused, “you think you’re funny now, but wait and see what I have in store for you” teacher chuckle comes in at a solid 9.
I’m told my **Mad James Mason Conquers The World Laugh ** is quite good. I’ve used it to make entire classrooms full of high school freshmen shut up and be quiet.
My Peter Lorre Nasal Giggle, on the other hand, stinks.
I do, however, do a very good **Dwight Frye Maniacal High Speed Giggle ** that seems to unnerve anyone I do it for.
Even when they know I’m kidding.
My cackle is highly rated, not only for its maniacal properties but for its piercing qualities. I’d only give it a 9.2, though; my mother had the Perfect 10 of a cackle, recognizable as hers without further identification needed, even through the tinny speaker of the sound being carried from an elevator in which she was trapped.
15 + … many many years ago late one night for reasons I can no longer recall, I started to Bwahahahaha. With no intent on my part, as though taking on a life of it’s own, it grew louder and more menacing, to the point where I was [seriously] starting to scare myself :eek: one of the gals who was there screamed “you’re fucking scary!!” and karate chopped me across the throat. I gagged and the noise stopped. I’ve never been able to recreate that noise again since …
I have an exceptional “Mwah-hahaha,” but most of the points come from the deranged expression that goes with it. (Classic squinty on one side/Manic on the other.)
I’ve been practicing the Mwaa-ha-ha-ha-ha-haaaa laugh since seventh grade (20 years ago), and the fruit of my labors is highly rated by those subjected to it each Halloween. I also do a throaty version of the same that’s very useful for scaring children. My high-pitched witch’s cackle turns heads, especially since it’s a most incongruous sound to be coming from a six-foot-three teddy bear.
I do a very respectable Vincent Price chuckle…
I normally have a loud attention getting voice. Putting full diaphram and projection behind a loud, booming Mwaa Haaa Haaa, and I can scare those meddling kids out of the house with little problem.
The fact that I am a big, ugly, guy who got my screen name due to my resembelence to a certain Muppet ogre, and the judges would be affraid to give me anything less than a 9.

When I’m at the top of my form, I’d say that my Vincent Price Maniacal Crescendo rates a solid 9.1 (with a 10 being Mr. Price himself). I’m sadly out of practice just now, however, and probably cannot manage an effort worthy of anything more than and 8.0.
My Chuckle of Urbane Evil[sup]TM[/sup] is probably an 8.5.
The fact that I’m very soft-voiced and normally laugh silently provides a bit of extra impact when I engage in evil laughter.

Sweetums has always been one of my favorite Muppets. If I may say so myself, I do a pretty darned good rendition of the “Hey, wait for me! I wanna go to Hollywood” scene from The Muppet Movie. Sends my daughter into fits of giggles every time.
