Lead singer Isaac Brock is an atheist. He had this to say on the subject: "I don't think I'm living wrong in the first place, so when the lights go out on me, and brighter ones come on and I have to talk to some guy with a big, bushy beard, or some big glowing blob, I think I'm going to be fine."
The song, "The Good Times Are Killing Me" is about the bands periodic indulgence in drugs, like pills, alcohol and marijuana. Singer, Isaac Brock has confessed to regretting how much and how often he used to do drugs.
Modest Mouse was mentioned, by name, in the Supreme Court case of MGM vs. Grokster. Supreme Court Justice, David Souter, wrote that on the Grokster P2P network, "Users seeking Top 40 songs, for example, or the latest release by Modest Mouse, are certain to be far more numerous than those seeking a free Decameron, and Grokster and StreamCast translated that demand into dollars."
During an April 2004 interview with Josh Modell of AVclub.com, Isaac Brock revealed that after a long night of drinking he returned to the apartment he was staying in while recording The Moon & Antarctica. He stepped outside to smoke a cigarette to find a group of 14 kids hanging around on the sidewalk. Being what he called a "friendly drunk guy," he decided to say hello, but before he could get the words out of his mouth, one of the kids punched him in the face, breaking his jaw. The random attack continued with the kids chasing the band's dog and continuing to punch Brock. This forced the band to cut back on Brock's vocals during recording of the 2000 album.
Guitarist, Jim Fairchild, has released three full length albums under the name All Smiles.
Drummer Jeremiah Green, can speak a little bit of Japanese and can be herd speaking Japanese in the song, "Night on the Sun."
