I've never heard anything quite like this before. These two lynx are fighting over a female, and for as little actual fighting that you'll see, they scream at each other like a couple of drunk college freshmen. I almost wonder if the fight is the screaming, and the one that makes the most horrible noise wins. Seriously, you'll want to put your headphones on if you're at work, because people are going to wonder what the Hell is going on at your desk if you don't. And, I'm thinking that if you record it, it would make for an incredible ringtone for that certain someone you don't want to talk to. Get ready, you haven't heard screams like this before.
And then check out the "Dumb and Dumber" clip. I'd be willing to bet Jim Carrey got his inspiration for the "most annoying sound in the world" from the lynx.
