Lions are pure instinct.

Shouldn't natural selection eliminate these people?

Muay Thai fighters try and start fights whenever possible.

Sounds like the engine.

Natural selection has failed.

Famous people who killed another person. A few obvious, more recent examples, but some that might surprise you (stick around for number 1.)

She's a natural.

It's one killer hula-hoop trick.

Love how the cat acts all natural. Like it was intentional.

Two of my favorite things, natural disasters and people who sound like extras from 'Dazed and Confused.'

We want to laugh at this guy because we think he might be retarded. Or a serial killer.

Obama is a killer. AN INSECT KILLER!

Springsteen, a champion of the underdog, now actually makes sense as an icon of Microsoft's dwindling market share.

What happens when a Japanese couple gives birth to a new baby? A stereotype is born.

Beyonce's performance at the BET awards was completely unmemorable, save for the fact that she DRESSED AND ACTED LIKE A FREAKIN' GOLDEN ROBOT! Why, bootylicious lady, WHY??

The Angry Leprechaun will surprise you as the secret killer in this spot-on parody of the "Zodiac" trailer. Oops, did we say it was a secret?

Nothing is better than some sweet vigilante justice.
