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.
