Barrymore said she felt "honored" to receive any sort of award from Harvard.
"When I was 13, and dropping out of school, I never would have thought that Harvard would call me and ask me to come celebrate my life," she said. "It's wild."
The light-hearted award comes at an appropriate time in her career, Barrymore said.
"I've realized that I just can't take it all too seriously. You have to be able to have a good laugh about yourself."
