Actor Seth Rogen began his hearing Wednesday joking with Health, Education, Labor, and Pensions Committee Chairman Tom Harkin, D-Iowa.
"I don't know if you know who I am, chairman. I know you never saw 'Knocked Up,' which is a little insulting," he said, adding that his presence at the hearing had nothing to do with the legalization of marijuana.
The C-SPAN video of Rogen's statement has already received more than 600,000 views on YouTube.
Rogen went on to discuss Alzheimer's and the devastating effects it had on his own family — much more serious than it is portrayed in the movies.
"The situation is so dire that it caused me, a lazy, self-involved, generally self-medicated man-child to start an entire charity organization," he said.
Later he joked about the reasons he came to the hearing.
“I came here today for a few reasons. One, I'm a huge ?House of Cards' fan. Just marathoned the whole thing, had to be here,” he said. “Two is to say, people need more help. I've personally seen the massive amount of financial strain this disease causes and if the American people ever decide to reject genitalia-driven comedy, I will no longer be able to afford it."
But after the laughs, Rogen got serious, reminding people with Alzheimer's that they weren't alone.
Although the hearing room was packed for the celebrity appearance, many senators were noticeably absent, which surprised Rogen.
"All those empty seats are senators who are not prioritizing Alzheimer's," he wrote on Twitter after sharing a picture. "Unless more noise is made, it won't change."
