Formation and secrecy (2016–2017) Prior to the formation of the band, Dallon Weekes and Ryan Seaman were longtime friends who had worked together in the past. Seaman joined Weekes' former band The Brobecks in 2008 and played drums for Weekes' solo projects, including the songs "Sickly Sweet Holidays" and "Please Don't Jump (It's Christmas)." Initially a solo act, Weekes had been writing and recording songs for several years while on the road with
Panic! at the Disco. Seaman performed drums on these songs, which eventually became their debut EP
1981 Extended Play, and Weekes proposed that they present themselves as a duo. The "I Dont Know How but They Found Me" moniker and project idea has existed since 2009. Uniquely, the punctuation of the band name is intentionally incorrect, with no apostrophe in "don't" and no comma after "how." Weekes credited it to his time in Panic! at the Disco, stating that in the band, "punctuation was a big deal, so I just wanted to take the opposite approach and get rid of it all." The band's name was inspired by a quote from the movie
Back to the Future. Weekes and Seaman began secretly performing in small venues from late 2016 to mid-2017. They debuted at Emo Nite Los Angeles's 2-year anniversary event on December 6, 2016. After the show, different sources wrote about a "new side project" by Weekes and Seaman and confirmed the band name. Even when confronted with photos and videos taken at the shows, Weekes and Seaman denied the project's existence for months. Weekes later stated that they did not want to exploit his and Seaman's name recognition and association with the well-known bands they played in. Seaman would depart his band
Falling in Reverse in May 2017, followed by Weekes leaving Panic! at the Disco in December.
