From Guy Kawasaki's 10/20/30 Rule of PowerPoint.

"I suffer from something called Meniere's disease-don't worry, you cannot get it from reading my blog. The symptoms of Meniere's include hearing loss, tinnitus (a constant ringing sound), and vertigo. There are many medical theories about its cause: too much salt, caffeine, or alcohol in one's diet, too much stress, and allergies. Thus, I've worked to control all these factors.

However, I have another theory. As a venture capitalist, I have to listen to hundreds of entrepreneurs pitch their companies. Most of these pitches are crap: sixty slides about a "patent pending", "first mover advantage", "all we have to do is get 1% of the people in China to buy our product" startup. These pitches are so lousy that I'm losing my hearing, there's a constant ringing in my ear, and every once in a while the world starts spinning."
