Like Samson's, a man's physical strength is directly proportional to the length of his hair, which is why The Beatles spent most of the 1960s crushing classical marble busts with their bare hands. Trade some strength for a new look with today's Groupon: for $20, you get two men’s haircuts from Abby Roberts Men’s Hairstylist, located in the Tru Beauty Hair Salon in Overland Park (up to a $50 value).

Gents looking for consistently well-groomed manes of manhood have trusted their tresses to Abby Roberts for 10 years. Hair therapy begins with a consultation and precut manipulation, in which styling dos and don’ts are diagnosed and immediately remedied via a precision haircut. Abby employs the gilded edge of a straight razor to purge neck skin of its mammalian accouterments. Once the noggin is relieved of excess follicle pressure, a shampoo massage cleanses locks and eases stress more easily than meditating on a cloud made of crème fraîche. The cranium retreat concludes with a final finish incorporating styling products. Camouflage coloring, which blends silver strands into their darker counterparts, may be added for $25.
