The profanity-filled course introduction video, which has over 300,000 views, was uploaded by Mehler on YouTube on Sunday.

At the beginning of the video, Mehler wears a space-like black helmet which he says is equipped with filters that cleans the air he breathes. He introduces himself as an alien to the earthlings and says, “intergalactic Internet is all abuzz about this planet, where suffering is through the roof.”

“I don't know whether you people have noticed, but it's dangerous to breathe the air,” he said. “Many of your experts are advising wearing masks because there's a deadly virus spreading around the planet. Your civilization is collapsing and life on your planet is going extinct.

Later on in the video, the professor tells the students he has no choice but to return to classroom to teach face-to-face. He urged his students not to come to class as it could expose him to the virus and risk of him suffering severe Covid symptoms are greater because of his age.

The 74-year-old told students they could fully participate during online classes, and they shouldn’t worry how remote learning would affect their grades because “no matter how hard you work, you have no control over your grade.”

“None of you are good enough to earn an A in my class,” said Mehlar. “So I randomly assign grades before the first day of class. I don’t want to know anything about you. I don’t even want to know your name. I just look at the number and I assign a grade. That is how predestination works.”

Mehler also told his students that they could go complain to the dean if they didn’t like any of his class rules. “I’m retiring at the end of this year and I don’t care any longer,” he said.

Mehler, who had been teaching at the university for the past 27 years, was put on administrative leave.

Many people fail to get the “intention” of the introduction, but others are with Mehler “100 percent.”
