Maryland Terrapins players Jaylen Brantley and Jared Nickens kicked off a worldwide dance craze last month.
They challenged people via their Instagram to do their own videos set to Ghost Town DJ's "My Boo" and it's amazing.
So many people are joining the craze that "My Boo" — first released in 1996 — has actually reappeared on the iTunes charts.
It started spreading among college athletes, like in this one.
Which was quickly one-upped by Rutgers.
But it didn't stop at the college level; the Dodgers tried one, hoping a giant bag of popcorn would help them stand out.
How do you celebrate the snapping of a 6 game losing streak?!#runningmanchallenge!!!!

Chris Evans sort-of-kind-of tried to do the original running man dance maybe on The Ellen Show, but let's include it because it's Chris Evans.
Fifth Harmony's Dinah-Jane Hansen did a pretty great running man video in a parking garage.

Even people in Japan are doing it!
Obviously, with a dance craze this popular, people are going a little nuts with it.
Yikes.
At least this guy used a green screen.
And if you're going to try it at home, just make sure you're not near any low ceilings.
So this happened
There are graduation ones.
This one gets extra points because they're all doctors.
This kid went overboard in the best way.
