Take the H.P. Lovecraft Historical Society:
SaniTest: How Insane Are You?
Your score is:119
For easier understanding, the HPLHS SaniTest assessment algorithm converts your raw score to a scale of 1 to 10. This number is your INSANITY INDEX.
INSANITY INDEX 6.43 Your SaniTest(TM) score indicates that you are utterly haywire. Your neural circuitry seems to be badly misfiring, with frightening and/or hilarious effects. You may find yourself capable of superhuman strength as a side effect, but don’t count on it. Others who scored at this level include entertainer Wayne Newton and skateboarding legend Tony Hawk.
