Tuesday was World Trick Shot Day and Harlem Globetrotter star Hammer Harrison came through with a great one. He did a parachute jump out of a plane at over 13,000 feet . . . and successfully slammed home a dunk right before landing. It’s being called the “world’s highest slam dunk,” and it’s pretty amazing that he nailed it on his first try. His tandem partner was a pro from Skydive Arizona.
