I Hate Monkeys from Call of Duty: Black Ops

Description: Kill 7 monkeys in under 10 seconds in the Rebirth labs.
Stallion Says: "Suck it, PETA!"
How to Get It: So far, Ray has confessed to virtually killing women, horses, and bears (oh my!), so we're not surprised to see this one on here as well. And, frankly, it's one of our favorites too. The easiest way to snag the achievement is with the grenade launcher, which you can find leaning on a desk in one of the offices. Fire a shot into the Central Labs area and an explosion will trigger, killing all of the monkeys. If that doesn't work, there is a corner with a number of caged monkeys hopping around that's fairly begging for an explosion to happen near it. You know what to do. If all else fails, just strafe 'em all!
