Seth Rogen Urges Senators to Get 'Knocked Up'

Seth Rogen testified before a Senate subcommittee Wednesday and pledged allegiance -- to "House of Cards."

Seth went to Capitol Hill to voice his support for legislation to increase funding for Alzheimer's research. Seth's mother-in-law suffers from the disease.

By congressional standards, Seth was hilarious ... and a little too hip for the room.

Safe to say Senator Tom Harkin, Chairman of the Senate Appropriations subcommittee, is not a big fan of "Knocked Up" ... but he was clearly amused.

Check out the video. Pretty funny.
