Kayla Harrison has her first win of 2025.

Currently ranked No. 1 in the MMA Fighting Global women’s bantamweight rankings, Harrison appears to be next in line to challenge Julianna Peña for the 135 pound title sometime this year. While nothing is officially booked, the two-time Olympic gold medalist is staying sharp, and recently one impish YouTuber found out just how sharp.

In a clip posted to social media, ImReddTV attempts to prank Kayla Harrison during a training session, stepping into the cage with her to “show her a few things.” Harrison appears to know what’s going on though and bids him to “bow to your sensei” before immediately taking him down with an o goshi hip throw. Harrison then moves into mount and feigns punches while ImReddTV quickly repeats it’s “just a prank,” but Harrison then armbars him anyway.

ImReddTV has a history of pranking UFC fighters, with things nearly going terribly wrong for him in a prank on Jamahal Hill a few years ago.
