Sure, LeBron James and Dwyane Wade have pulled off some ridiculous alley-oops in Miami, but the Heat have nothing on a group of seven guys who joined forces to create one of the most incredible Vines of the summer.

In what looks like a backyard pool, seven friends pull off an incredible alley-oop. Through a combination of sweet passes and well-timed jumps, these guys have created an instant hit.

Take a look:

The Vine was posted by a user named "Dom," who appears to be "@ThisKidDom" on Twitter. He says it took dozens of tries to complete the dunk.

Talk about perfect timing. Not only do they all carry out their roles to perfection, but they do it in under six seconds. Well done, boys.
