Besides being an actor, musician, and songwriter, Dennis Quaid is also a jet pilot, low handicap golfer, and armchair historian. He has powered a NASCAR around an oval track, played golf with 2 presidents, spoke before Congress, piloted a dogsled in the arctic, meditated on the shore of the Ganges River, run marathons, been a middle-weight boxer, and can change a diaper in 20 seconds. Like him, all of Dennis's famous friends have interests outside of the thing they're known for.
