Good luck shaping your reality at the 15th annual New York International Fringe Festival, which brings 200 crazy-mad and serious theater/dance troupes from across the city and around the world to perform at more than 20 downtown venues.

We've picked seven attractions from North America's largest performance festival, which in previous years spawned "Urinetown" and, yes, "Debbie Does Dallas." But, really, check for yourself at fringenyc.org, or call 866-468-7619. Tickets are $15 in advance, $18 at the door. For addictive personalities, there is a $70 Fiver Pass, a $120 10-play Flex Pass and, you poor darling, $500 for an all-you can-see Lunatic Pass.
