Please. Make. The Laughing. Stop.

A baby laughing is cute, a Yogi laughing is disturbingly entertaining, but the sound of the following woman laughing is something straight outta Nightmare on Torture Street. Consider yourselves warned. (And here's a challenge. The video is a whopping 6 minutes and 40 seconds long. I'd otherwise edit this, but I want to know how long you can sit through it without scratching your eardrums out. I lasted a mere 1:44.)
