I got invited to invest in a monkey knife fight arena. It is actually quite lucrative and not illegal, per se. What we do is take between two and twenty vervet monkeys and give them combat knives (some times we mix it up and give them battle axes, throwing stars or sectional staff). Then we feed the monkeys crank the we get from this pink loving hippie cop down in LA. Like lots of it. See, what happens then is we toss a raw steak in the middle of a pit and they frantically dismember each other to get at it. Alternately you can tie the hands of the monkeys together a la "Beat It" and have a '2 ape enter, 1 ape leave' sort of thing going on. Obviously the real money is in having your own stable of monkeys but normal betting rules apply. Addy in profile for anyone wanting stock.
