It seems like liberals truly love to bash on presumptive GOP nominee Donald Trump in their commencement speeches for colleges and universities this season. Both President Obama and his wife have done it, and Spanish Univision anchor Maria Elena Salinas has also followed suit. Now, an infamous and highly liberal Hollywood actor made another swipe at Trump in his commencement speech to the Massachusetts Institute of Technology (MIT).

Hollywood elite, Obama sympathizer and Hillary supporter Matt Damon spoke to the graduates on Friday and passed on advice he got from former President Bill Clinton.

The actor grew up near the MIT campus and played a mathematically gifted MIT janitor in “Good Will Hunting.” Damon, who dropped out of Harvard to pursue his acting career, said being a keynote speaker was an honor he didn’t deserve. And to be honest, he still doesn’t deserve it.

In a wacky theory that the world is part of an advanced alien species computer simulation, Damon somehow illogically connects this theory to Trump’s rise amongst American voters in his speech.

“If there are multiple simulations, how come we have to be in the one where Donald Trump becomes the Republican nominee for president? Can we transfer to a different one? Not every problem has a high-tech solution. We can’t science the you-know-what out of every problem,” Damon said in his address to the students. The last line of that address was quote from his latest film “The Martian.”
