The challenge is in honor of Movember, the movement to grow mustaches to raise awareness for men’s health during the month of November. Fallon asked fans to flip a permanent marker, catch it with one hand, uncap it, and draw a mustache on their face—all in one fluid motion.
It’s harder than it looks, apparently, as Fallon joked it only took him “43 times” to get the movement down himself.
On The Tonight Show Starring Jimmy Fallon Tuesday, the host revealed some his favorite submissions. People got creative, of course, and the clips included dabbing, sassy comments from kids, and some fancy video editing. One devoted fan even shaved his real mustache on camera before replacing it with a Sharpie squiggle.
According to Fallon, thousands of folks submitted #Sharpiechallenge videos across TikTok, Instagram, Twitter, and Facebook. Here are a few that didn’t make it on the show.

The challenge seems to work best if there’s not an actual mustache already on your face. And as The Tonight Show helpfully noted in a YouTube comment, if you find yourself wondering how to get Sharpie ink off your skin, try oil-based makeup remover or rubbing alcohol.
