If you'd like the superintendent to shovel snow, better ask nicely.

17-year-old Leonardo Semma was suspended from his Michigan high school back in January after he, uh, colorfully asked said district official to take care of the snow in the school parking lot.

To commemorate his graduation, he posted screenshots of the infamous Twitter exchange on Sunday, along with his notice of suspension.

"Greatest achievement of my high school career," he wrote.

It all started when superintendent Kenneth Gutman tweeted to apologize for the district for not having the parking lot sufficiently plowed after a snowstorm.

But Semma, who had already slipped on ice that morning, and whose friends had almost been injured themselves, had a few choice words for Gutman.

"Sorry's not going to melt the snow," he wrote. "Grab a shovel and get your ass out here at 5:30 sharp boi."

Unfortunately for Semma, the school district deemed his tweet a "use of profanity" and suspended him from school for three days.

Semma's tweet summarizing his experience has gotten over 61,000 retweets since Sunday.

His parents also received an email from the principal, who is letting Semma's insubordination haunt him even beyond graduation.

Hey, snow-covered roads are dangerous. Someone's gotta speak up.
