In addition to keeping surfers warm, a wetsuit can act as an aerodynamic infant body suit or formal attire for an under-the-sea prom, with the addition of a Jacques Cousteau-themed necktie. Don this versatile vestment with today’s Groupon: for $90, you get a one-hour surf lesson for three people from Greco Surf (a $180 value).

Certified in both CPR and first aid, the laid-back Surf Academy professors at Greco Surf teach both beginner and advanced tide rippers how to master the art of surfing. With flexible lesson times and a willingness to meet in several locations across Orange County and Los Angeles, Greco Surf's instructors specialize in teaching neophytes on foam surfboards rather than wooden chessboards. When not wave wrangling, the outfit sponsors a surf ministry that raises money to send teams to Central and South America along with boards and clothing to build houses for families in need.
