Funny Sells 15,000

If you're trying to come up with a business idea, think funny. Funny sells.

Well, not all funny. But it's pretty interesting how you can take an ordinary product and create a humorous version of it - and all of the sudden people are searching to find out where they can buy it.

This is the case for knit caps made by Beard Head. A knit cap is nothing new. In fact some people have several of them - why would they want another?

However, Beard Head decided to create knit caps with mustaches. If that isn't a funny enough visual for you, they took it a step further: knit caps with interchangeable mustaches. Yes, you can switch out your knit mustache depending on what mood you're in.

If you don't see yourself wearing one of these beauties, you probably already know someone it would look beautiful on. And who wouldn't want to be the proud gift-giver of this item?

See what just happened here?

Funny sells. The hat isn't warmer, cheaper, softer or more convenient. It's just funny. And the company sold 15,000 last year, according to Entrepreneur Magazine.
