Not only are Warren Buffett's Christmas cards unconventional, but so is his daily breakfast, or should I say everyday diet:

How does the world’s top investor, at 84 years old, wake up every day and face the world with boundless energy?

"I'm one quarter Coca-Cola," Warren Buffett says.

[…]

…"If I eat 2700 calories a day, a quarter of that is Coca-Cola. I drink at least five 12-ounce servings. I do it everyday."

When watching a documentary about Warren, we learned that he ate one steak everyday, so this diet of his didn't come as a big surprise. If that works for him, it works for him, but I would definitely begin to feel sick within a few days.

And yes, from the article you can tell that he's into potato sticks as well.
