Check out Russell Holden, Wesley Huitt and Jordan Harvell of Mildred High School pulling off a Globetrotter like double alley-oop in a game.
Luckily the guy under the basket didn't try to go for the block or he would have ended up rolling on the floor like this kid...
We've also seen a few impressive double alley-oops in the NBA in between these two videos. My favorite will probably go to Jamal Crawford and Blake Griffin for this 2014 play.
