The ad included a listing of amenities that came with the school, like a new athletic field, plenty of parking and a "bigger than normal dining room," according to WDAF-TV.
But district officials said the problem with the ad was the reason for the sale. Scheele wrote the school was being sold "due to the loss of students coming up," WDAF reported.
“I decided to say the reason we’re selling this is because of 'the loss of students,' because the senior class is graduating,” Scheele said.
The teenager said he apologized for the joke, but school officials weren’t laughing and gave him the harshest penalty possible, suspending him from the school’s graduation ceremony.
The American Civil Liberties Union of Missouri has since filed a lawsuit against the school district, contending the harsh punishment violated Scheele's free-speech rights.
