John Patrick Douglass (born June 30, 1988), known online as jacksfilms, is an American YouTuber, comedian, filmmaker and musician. He began his online career in 2006 when he created his YouTube channel. His channel initially consisted of infomercial parodies, sketches, and comedic music videos. As his audience grew, he expanded into comedy series centered around viewer comments and submissions, such as Your Grammar Sucks (YGS), in which he makes fun of incorrect grammar, JackAsk, in which he answered questions about himself (often satirically), and Yesterday I Asked You (YIAY /jaɪ/), initially a segment at the end of JackAsk and later became a standalone series, in which he asks questions to his audience, and they give answers. In October 2020, Douglass announced the end of YGS and JackAsk.
