Commencement speaker J.K. Simmons needs you to stop saying 'literally'

Oscar winner J.K. Simmons isn't used to performing monologues he wrote for himself, but he gave it a go as commencement speaker for the University of Montana 2016 graduating class Saturday.

"Over the years, with education and experience, I have gotten to be pretty good and feel pretty comfortable with other people's words," Simmons, a UM graduate, himself, said from the podium. "Here, I'm just me. I'm not pretending to be someone else, and I'm speaking my words, not words that were written for me."

Those words of wisdom that came straight from Simmons, a self-described "curmudgeon" who likes to "moan about how things were better in my day"? Here are a few:

• Eat your vegetables
• Use your turn signal
• Be on time
• Call your mom and dad (which is something he also emphasized in his Oscar acceptance speech)
• Be present "and not staring at your damn smartphone all the time"
• Stop saying "literally"

"Dear God, please only use that word 'literally' when it actually makes sense," he said. "Seriously, if you take nothing else from my remarks today..."

Here's the actor's full speech:

Other celebrities donned cap and gown recently for commencement activities including:

Ryan Seacrest at University of Georgia

The American Idol host returned to Athens, Ga., Friday night to receive an honorary degree and make his mom happy. She's "been waiting 24 years to see me" in graduation garb, he joked, though he later gave students this nugget of wisdom: "Make sure you happen to the day instead of it happening to you, but no matter the circumstances, you still only get one shot to make a day that matters."

He also made some social-media magic with the mascot Hairy Dawg. Obviously.

Here's Seacrest's full speech:

Paul Feig at USC film school

A 1984 graduate from USC, the Ghostbusters director stopped by the School for Cinematic Arts and told future filmmakers in the Class of 2016 to, well, not be jerks:

"You want to make something great, but be cool while you’re doing it so people will hire you again. Because if you screw up and you’re an (expletive), they won’t hire you again. But if you’re nice and you screw up, then they’re like, ‘Let’s give him another shot…’ It will buy you one free pass."

Here's an excerpt from Feig's speech via The Wrap:

Gregg Allman at Mercer University

The Allman Brothers musician shared the stage with former president Jimmy Carter Saturday, and was awarded an honorary academic degree at Mercer University in Macon. Allman treated the Class of 2016 to a performance.
