MERIDIAN, Idaho – Heritage Middle School student Dane Wissenbach schooled one of his teachers this week in front of the entire school, and it’s a lesson the educator will never forget.

During a staff versus students basketball game caught posted to Instagram this week, Wissenbach took the ball down court in the packed gymnasium, where the eighth-grader was met by math teacher Bryce Gillespie at half court.

Gillespie appeared to be playing tight defense, but Wissenbach was unconcerned and stunned the teacher with four quick crossovers that left Gillespie on the ground just outside of the three-point line. The teen’s moves literally crossed his teacher up so badly Gillespie reportedly dislocated his knee and required two colleagues to escort him off the floor, CBS Sports reports.

“The crowd didn’t do Mr. Gillespie any favors, either, getting lit as h-e-double-hockey-sticks,” according to USA Today. “One student even got in the teacher’s grill and mocked him as he limped off the court. Ouch.”

Wissenbach posted a video of the incident to his Instagram account with the caption “told him not to reach.”

If it wasn’t bad enough for Gillespie, the videos have since gone viral, with Wissenbach’s clip garnering 56,000 views and more than 400 comments in just a couple of days, and hibs_5’s reaching 16,000 viewers.

“Aye yo,” superduperdustin wrote in response to Wissenbach’s post. “I hope you didn’t say sorry.”

“Legend,” Jacob.perez81 added.

“I’m dying Dane you have made everyone here at Rocky proud #ripgillespie,” treybreeze wrote.

USA Today’s Ben Rohrbach also chimed in on the killer crossover.

“All of this ignores the two other teachers who erased Wissenbach’s would-be assist with a savage takedown of another student driving to the bucket. That’s a Flagrant 2 and an automatic ejection, right?” he wrote.

“The lesson, as always: Staff should always be on complete cruise control in these games, because any effort whatsoever is a lose-lose proposition. The best a teacher can ask for is beating a 14-year-0ld at basketball. The worst? You’re Mr. Gillespie.”
