Entrepreneurs often are adept at combining a personal skill or interest with business savvy to create a new enterprise. But what happens when a person's area of expertise is a little, well, unusual? As in fire-eating and snake-charming type of wacky. The enterprising performers on this list have created businesses out of teaching their special talents to others. And as it turns out, the businesses behind these schools are growing. Revenues in the fine-arts schools category, which as unlikely as it may sound includes such training, are projected to increase by nearly 3 percent this year to $4.73 billion, says industry research firm IBISWorld. By 2015, revenues are expected to jump to $5.72 billion. That's a lot of clowns, dancers, musicians, sideshow performers -- OK, you get the idea.

Ever wonder what it's like to flip through the air, your adrenaline pumping as you swing from bar-to-bar high above the ground? If so, the Trapeze School of New York might be for you. (Acrophobics need not apply.) The school offers classes for all skill levels, as well as intensive multisession workshops for more advanced "flyers." While the number of students varies annually, the school can collectively host as many as 100,000 classes a year, according to co-founder Jonathon Conant. He says the best part about running the trapeze school is the opportunity to see people "pushing their limits" and "learning to trust themselves and others more fully." We bet it's the thrill of it all, too.

Chuckling. Giggling. Snorting. Call it whatever you like, but laughter is considered by some people to be therapeutic. After studying in Mumbai with trainer Madan Katari, Vishwa Prakash opened Yogalaff, a classroom in Midtown Manhattan that attracts students of all ages and nationalities to practice "yoga laughter" -- a unique form of yoga that triggers laughter. While anyone can attend his weekly public classes for free, Prakash makes money teaching classes for corporate clients, which can start at $250. Combined, Prakash estimates that he shares a good laugh with roughly 2,000 people each year.

That's when the Scratch DJ Academy was born.

The legalization of medical marijuana in states like Maine, Vermont and California has created more than just controversy. For Richard Lee, it opened an entrepreneurial window. The former Aerosmith roadie became a staunch cannabis activist after an accident in 1990 that left him paralyzed from the waist down. In a bid to help legitimize the cannabis industry, Lee in 2007 opened a school that focuses on the business behind the plant, which is known commonly as a recreational drug and can be used to make products like clothes and paper. At Lee's Oaksterdam University, the curriculum focuses on cannabis-related topics including politics, legal issues and horticulture. The school hosts approximately 4,000 students each year.
