Imagine: She has her hair pulled back in a taut bun and is wearing short heels and an even shorter skirt. The stem of a (we hope) thornless red rose is clenched between her teeth. He has his hair slicked back and is dressed in tight jeans and a shirt that won't show too much armpit sweat. The heavily rhythmic music begins and off they go, dancing so closely that only a body condom could stop the pheromone exchange. Now is that a hot first date or what? Taking a tango class is the best way to cop a cheap feel and show your partner that you aren't afraid of a cultural education. Lessons are held every Monday through Thursday from 8 to 10 p.m. and Friday from 8 to 8:30 p.m., and even beginners can walk in anytime, so there's no need for much advance planning. The cost for each class is only $15, and there's no obligation to join. What else do you want? A freakin' bed, some baby oil, and a candle?
