The best way to make someone believe you've gone insane.

[ToxicOranges]

Well sir, you have to dress like this chap:

And say, "Wubble" repeatedly.

EDIT: Dammit. Ninja'd. I got an image though!

Talk to the person you wanna convince about seeing people that aren't there, because when you turn away for a sec and then look back, they're gone, and couldn't possibly have left that quickly. Or that sometimes when you are all alone at home, you think you hear someone call for you, when noone's around. Or that you constantly get thoughts of committing suicide. Not quite as severe as the crazy shit in this thread, but the subtlety is what makes it convincing.

... and now I just admitted that I'm crazy. Ah well.

Fight someone over furry drama.

It's like Godwin's Law, only with "insane" instead of "Nazi".

 

[Thespian]

Write a single message over and over again on a wall and act like some small detail is just wrong. Get angry if people act in anyway other than total agreement.

This is a good one.

Or, ask for gardening supplies such as ammonia based fertilizer and arrange it in little concentric piles and patterns in your room so people think it all makes sense inside your head but really you are just making mustard gas and napalm, biding your time until you set off the bombs, murdering everyone around you.

It may cost you your loved ones, but hey, it'll work.

Stick two pencils up your nose, underwear on your head, and add "wibble wibble" into your fractured sentences.

I hope someone knows this line lol
