Fathers, our rarest natural resource, must be extracted from the soil and dusted off before being transmuted into free lunches or sagely advice. Refine your relationship with today’s Groupon: for $17, you get two tickets to the San Diego Natural History Museum to be used on June 17, 18, and 19.

The San Diego Natural History Museum has transported visitors into the past for almost eight decades. The recently opened Ends Of The Earth exhibit lets museum-goers watch explorers conquer terrain in the multimedia theater, put on a penguin suit and slide like the birds themselves, or challenge a live polar bear to an ice-eating contest. Illuminate history through the Fossil Mysteries exhibit's life-size models of ancient animals, such as dinosaurs and mastodons, as well as a fossil aquarium featuring actual whale bones on display. Dads and future dads looking to enjoy 3-D movies without braving the multiplex's gangs of candy-craving teens can use the included tickets to catch The Ultimate Wave Tahiti, starring champion surfer Kelly Slater, or Turtle Reef 3D, from the award-winning producers behind museum mainstay Ocean Oasis.
