Check community papers, local message boards, the YMCA and community centers for free or inexpensive dance lessons. Many dance studios offer special first-timer promotions that allow newbies to take classes for under $10, sometimes for free. If you'd prefer to step on each other's toes in private, the Internet is loaded with DIY sites like WikiHow and eHow on which free video instructionals teach you basic steps to the tango, waltz and, if you're in the mood, the Robot and the Worm.
