John Patrick Douglass (born June 30, 1988), also known as his pseudonym jacksfilms, is an American YouTuber, videographer, musician, and sketch comedian. He is best known for his series Yesterday I Asked You (YIAY) and the now discontinued Your Grammar Sucks (YGS), in which he comments on content sent by fans. Douglass' career on YouTube spans over 19 years.
Douglass, who was born in Columbia, Maryland, created his main YouTube channel in 2006. His content was initially focused on parodies, music videos, and sketch comedy, or a combination thereof. Douglass has referred to this series of videos as PMS (parody, music, sketch). His musical output includes both parodies of popular songs and original content. In 2011, Douglass began Your Grammar Sucks, in which he reads comments with excessive grammatical errors. Douglass created the Jackask series in 2014, where he answers user-submitted questions satirically.
