Having to wait for wet nail polish to dry curbs people's natural urges to plunge fingers into frosting or tickle the mailman too hard. Conquer temptation with today's Groupon: for $16, you get a manicure and a pedicure at QQ Nail Spa (a $32 total value). This deal is valid at all four Manhattan locations.

QQ Nail Spa's staff of nail-buffing technicians treats clients to pampering services that improve both their cosmetic appeal and sense of well-being. A manicure (a $10 value) sculpts digits into tidy shapes so that customers will feel attractive while scratching and sniffing stickers. The pedicure (a $22 value) polishes toenails to a high sheen before applying a fresh coat of cuticle paint. During the latter treatment, clients rest atop a massage chair that eases them into a state of relaxation normally reserved for caterpillars with the foresight to fill their cocoons with memory foam.
