This is the title track of American Alternative Country collective Lambchop's 11th album. The LP was originally titled "Mr. Met" after the New York baseball team's ball-headed humanoid mascot, but was changed to Mr. M at the insistence of lawyers. Frontman Kurt Wagner explained to Mojo magazine: "I was playing with the past participle idea of the word 'met,' making it a sort of subtle reference. But for me personally, the baseball mascot Mr. Met is something some friends that I'm close with share a fondness for, so it's kind of an open letter to my friends - which is the way I approach music anyway. Unfortunately when our new record company was aware of the title, they tried to get permission to use the name and couldn't."
Wagner explained the song's meaning to UK newspaper The Sun: "I like to think of it as a guide book or maybe a little self-help primer based on certain personal events," he said.
