Get ready for another “Boy Meets World” reunion … but this one might not be the happiest reunion. Cory’s (Ben Savage) old bully Harvey "Harley" Keiner’s (Danny McNulty) guest appearance on “Girl Meets World” was announced in the spring, and the episode will air Friday, Oct. 10, TV Line reports.

Last time audiences saw Harley, he was bullying Cory and donning his signature leather jacket. Harley’s mean ways eventually got him sent to reform school in “Boy Meets World” Season 3.

Harley seems to have given up his bullying ways in “Girl Meets World” and traded in the leather jacket for coveralls. He won’t be causing trouble for Cory in the episode -- in fact, he might even be keeping Farkle (Corey Fogelmanis) and Lucas (Peyton Meyer) out of trouble. Harley is now the janitor at John Quincy Adams Middle School, and the boys will be assigned to work with him during a lesson on appreciation.

It doesn’t seem like the kids are thrilled with their assignments. While Lucas and Farkle are cleaning up after everyone with Harley, Riley (Rowan Blanchard) and Maya (Sabrina Carpenter) will be working in the cafeteria.

This won’t be the first time Cory’s students will meet one of his old classmates from the "Boy Meets World" universe. Minkus (Lee Norris) was revealed to be Farkle’s father, and Shawn (Rider Strong) is also set to return on the spinoff. Check out TV Line for more photos of Harley’s appearance on "Girl Meets World."
