How to laugh evily like Juju often does.
You should know, before you start, it isn't that hard to laugh evily.

You NEED:
A person to teach this to (e.g. yourself)
An evil spirit... (It does work without...)

You (highly recommended) need:
Someone who is easily scared to practice on

You (might) Need:
Water at hand.

Instructions.

1. First, just practice saying Hehehe for a minute. Hehehe As in he, As in he she
2. Then, once you have mastered that, prepare your evil spirit to do it evily
3. Spread your mouth out as far as it will go <<<<that way>>>> (Recommended for beginners)
   
4. Put your tongue at the top of your mouth so it is touching your top teeth.
5. Start saying Heh heh heh heh
6. If that doesn't sound right, Congratulations. You can skip the next steps. If not, proceed to step 7.
7. Have you got your evil spirit? Think about evil things, like the awesome color black.
8. Try again. Try deepining your voice, making it lower.
9. Try to smile, it stretches your face wider, and makes you look eviler
10. If you haven't mastered it, sorry, I have no more advice for you except to practice.

Notes: If you have a dry throat, drink. If you have someone to practice on, try to freak them out.
