Tim Yohannan (August 15, 1945 – April 3, 1998), also known as Tim Yo, was the founder of Maximum Rocknroll, a radio show and fanzine documenting punk subculture. He also helped in establishing a number of DIY collectives, such as 924 Gilman Street, Blacklist Mailorder, and the Epicenter Zone record store.
As a self-appointed "punks' herdsman", Yohannan had a reputation as being notoriously difficult.
The band Green Day recorded the song "Platypus (I Hate You)", "Take Back", and "Prosthetic Head" on their 1997 album Nimrod. The songs do not directly mention Yohannan. However, frontman Billie Joe Armstrong tweeted on February 17, 2011 (and deleted the tweet a few hours later), "Platypus was written for Tim Yohanon. And I pray to god I misspelled his name. Rest in shit you fucking cunt". The song "Ha Ha You're Dead" from the band's album, Shenanigans, was also written about Yohannan after he died.
