Until Wednesday, February 26th actor Seth Rogen was most notably known for his roles in such new age comedies as The Pineapple Express and This is the End, both heavily laced with blue collar humor and drug references. And then he testified before Congress on Wednesday to support Alzheimer's Research.

Rogen and his wife know first hand how the disease can effect a family (Rogen's mother in-law suffers from the disease). Together they founded the charity Hilarity for Charity aimed at empowering college aged students to volunteer their time.

His speech on Capitol Hill was both hilarious and heart-warming. Check it out below.
