Scientists say the average belly button is full of bacteria. A recent study suggests 2,000 different species live in belly buttons -- many of which they couldn't identify. That's why I'm going to invent a belly-button cleaner.

It will look like a really big, fluffy cotton swab. I don't want it to hurt, and I don't intend people to be digging in there too deep.

But let's be honest, whenever you clean out that belly button lint it stinks. There's gross stuff in there and you shouldn't just be OK with it!
