SILVER SPRING, Md. – Officials at Montgomery Blair High School are steaming after someone streamed soft core porn onto the cafeteria television at lunch time as a senior prank.

The Sun reports “furious staff members” at Montgomery are working to track down the student or students responsible for the prank Tuesday, when a streaming video of women gyrating their butts in skimpy underwear played in a packed lunchroom for about 30 seconds.

Twitter user @willism29 posted a video of the incident, which seems to have been taken down since. The Sun captured the unedited video and reposted it on the news site.

The video shows students gasping and laughing as a woman flashed on the screen, shaking her behind. The video briefly panned the room to show several dozen students staring at the television, which was mounted high on a wall along the ceiling. As the video flashed to other women in poses amplifying their assets, a school official walked up to the television with a broom and shut it down. When the television rebooted, it was connected to YouTube.

Mashable reports “school administrators are currently searching for the porn perpetrators.”

The Twitter video prompted several reactions online, most from Blair students laughing about the incident and mocking school officials.

“*Mom: ‘How was your day @ school honey’ Blair Student: ‘Ehhh we just watched some cheeks,’’ @Yeahhh_Man wrote.

“Blair won’t rest until they find out who did it,” @queensaroni_ posted along with a crying emoji.

The Washington Post reports Montgomery Blair High School is “a hub of science and math achievers in the Washington suburbs” that produced the 2016 National Science Bowl champions.
