Demi Adejuyigbe knows how to commit to a bit.

The taxi sex videoscomedian has been heralding in every autumn with a tribute to Earth, Wind & Fire -- dancing to their eternal banger "September" every September 21.

The tradition started in 2016, when he tweeted a video of himself grooving to the song. Wearing a t-shirt that reads "SEPT 21" on the front and "THAT'S TODAY" on the back, Adejuyigbe's tweet went viral for being freaking fun.

But then he followed up a year later -- this time, he jazzed up his performance with a red curtain.

Wearing another September shirt Adejuyigbe jammed in front of the curtain until the iconic chorus began. Ducking out of frame, he dropped the curtain to reveal a festive display of balloons and banners reading, "SEPT 21 -- THAT'S TODAY."

In case you forgot what day it is, obviously.

Adejuyigbe didn't forget this year -- this time, the video featured an unnamed person playing the opening bars of "September" on a keyboard. Then, a curtain dropped as Adejuyigbe danced across the frame, tearing off his blazer to reveal a t-shirt that said "SEPT 21" -- would you expect anything else at this point?

When the curtain lifted, it revealed the West Los Angeles Children's Choir belting out the chorus of "September."

Complete with confetti and streamers, the kids sang in front of a wall that said "SEPTEMBER 21 -- THAT'S TODAY."

It's pretty freaking adorable.

Even better, this year his video is being used for good.

"Each year on 9/21 I do a dumb dance," he wrote. "Now it's for charity."

His signature SEPT 21 shirts are being sold online, and 100 percent of the proceeds will be donated to RAINN, RAICES, and the National Center for Trans Equality.
