Jason Keith Pargin (/ˈpɑːrdʒɪn/;[1] born January 10, 1975) is an American humor writer and novelist who formerly wrote under the name David Wong.

Alongside John Dies at the End and its three sequels, Pargin has also authored three books in the Zoey Ashe series and one standalone novel, I'm Starting to Worry About This Black Box of Doom.

[2] He and fellow Internet writer John Cheese (real name Mack Leighty) attended high school together and met during an art class they shared.

Pargin used the feedback from people reading each episode of the webserial to tweak what would eventually become the book, John Dies at the End.

Pargin has described a disconnection between the old Cracked print magazine and the humor site Cracked.com due to multiple relaunches and almost entirely new staff.

[8] In a popular article published at Cracked.com, Pargin coined the neologism "monkeysphere" which introduces the concept of Dunbar's number in a humorous manner.

[10] When Pargin started PWOT, he took on the pseudonym of David Wong to keep his real and online lives separate.

[18] After enjoying some success John Dies at the End came to the attention of Don Coscarelli, who decided to adapt it as a film.
