Hahaha in an evil laugh would be displayed in the following context:
1) Buahahaha (evil witch type, mainly Wizard of Oz)
2) Muahahaha (evil villian type, the Joker off of Batma)
3) Heeehehee (old guy with asthma)
4) Duhhahumdeeha (average laugh of any wrestler, take Birdman07 or Fris Kris)

P.S. Fris, we should have an Avatar Smackdown, RAW = WAR.
