Penn State alumnus and famous actor Ty Burrell reminded students to “Mask Up Or Pack Up” on Friday.

Burrell was featured on Penn State’s Instagram story in a three-part, Cameo-style video.

Burell begins the video by introducing himself and using the slogan “Mask Up Or Pack Up,” which is part of Penn State’s latest public health campaign.

“20% of you say you won’t be wearing a mask this fall,” Burrell said. “If that’s the case, there’s a high probability that 100% of you won’t be learning in person.”

The video ends with Burrell pleading for students to “please, please put on a mask,” followed by a classic “We Are!” chant with his mask on.

Burrell is best known for playing Phil Dunphy in ABC’s Modern Family. He is a two-time Emmy winner and nine-time nominee for the “Outstanding Supporting Actor in a Comedy Series” award for his role. He is also known for his roles in Black Hawk Down, Finding Dory, Dawn of the Dead, and many Broadway shows.

Burrell earned a Master’s degree in Fine Arts from Penn State and was a member of the Theatre 100 Company during that time.
