Jack Douglass
John Patrick Douglass (; born June 30, 1988), better known as jacksfilms, is an American YouTuber, videographer, musician, and sketch comedian. He is best known for his series Yesterday I Asked You (YIAY) and Your Grammar Sucks (YGS), in which he commentates on content sent by fans. Douglass' career spans over 15 years on YouTube.
Born in Columbia, Maryland, Douglass 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.
In 2015, Douglass started Yesterday I Asked You, originally a segment within Jackask, where he asks his audience questions and reads humorous responses. Originally intended to be a daily series, new episodes are released every few days. Yesterday I Asked You is Douglass' most successful series, with over 600 episodes as of 2024. He has adapted it into various other formats, including a board game, a book, a YouTube Originals show, a tour, and an online party game with Be Funny Now. Since 2020, Douglass has streamed regularly on Twitch.
Douglass has collaborated with a variety of other YouTubers, including PewDiePie, Markiplier, RoomieOfficial, h3h3Productions and Dan Bull. The hundredth installment of Your Grammar Sucks includes contributions from jacksepticeye, Rhett and Link, Ryan Higa, and Vsauce.
