Eastham, a professor at Oklahoma State University, sent a parody video of the “Cups” song to his students before uploading it to Facebook.
“I love teaching at Oklahoma State University! Here’s the end-of-semester video I just sent to my OSU Entrepreneurship students in Spears Business,” Eastham wrote. “It’s not quite Pitch Perfect. Apologies to Anna Kendrick fans.”
Eastham’s a cappella performance, recorded in an empty classroom, uses cups as percussion as he sings:
“Semester’s over, now the grades are in,
Some are happy, some are sad.
But regardless of which letter grade you’ve earned,
I hope that you have learned.”
The song became popular after Kendrick performed it in the 2012 movie “Pitch Perfect.” It is a version of the Carter Family’s 1931 song, “When I’m Gone.”
