Due to a disturbing decline in dance lessons, most Americans can't tell a tango from a mango, let alone a mambo from a black mamba. Today's Groupon will help you avoid accidentally sweeping a venomous snake off its lack of feet: for $25, you get three 30-minute private dance lessons for an individual or couple, six adult group lessons, or six juniors group lessons (for students ages 10 to 16) at JitterSwing Dance Clubs (up to a $60 value).

JitterSwing's spirited instructors school students in a global gamut of dance styles during twice-weekly classes. Private lessons in the Social Swing, also known as St. Louis–style swing, entwine leg roots with cultural roots, and the Stationary Cha-Cha inspires rhythmic hip swiveling. Singles or couples can flow through the romantic River Waltz or Nightclub 2-Step as demonstrated by a hip-wagging chaperone. One-on-one lessons can also include styles such as the West Coast Swing, traditional Country 2-Step, or Line Dancing, ideal for lending artistic relief to café lunch lines.

JitterSwing's one-hour group classes encourage partner switching, allowing dancers to mingle, twirl, and exchange whispered lullabies with a variety of partners. Sample any of the aforementioned styles or spice up a slow weeknight with Salsa lessons or the more adventurous Swango (swing meets tango). Following private or group lessons for adults on Wednesdays and Fridays, high-energy hoofers enjoy free admission to dance sessions. Juniors can enroll in special sessions of the West Coast Swing, and those ages 16 and up may partake in the regulation-sized offerings.
