* "A Boy Named Sue".
--> "MY NAME IS SUE! ''HOW DO YOU DO!?'' '''''NOW YOU GONNA DIE!'''''"
--> "And if I ever have a son, I think I'm gonna name him... Bill! Or George! Anything but Sue, I still hate that name!"
* "Chicken in Black", which is often claimed to have been recorded as a TakeThat to Creator/ColumbiaRecords, who had been treating him poorly for years (though Robert Hilburn's biography ''Johnny Cash: The Life'' reveals this isn't the case at all: Columbia offered the song to Cash, who loved it and had no trouble recording it, only to lose interest when his colleagues disappoved). Ironically, it actually became a hit and raised his status with Columbia for a time. The best thing about it is that John's delivery is pretty straight-faced and serious. Also had a legendary tongue-in-cheek [[https://www.youtube.com/watch?v=y_uM87NTFW4 music video]], complete with chicken brain transplant!

In 1967, he even released an entire album of comedy songs, ''Everybody Loves a Nut''.
* During "I Walk the Line" on the San Quentin album he [[NotSoStoic cracks up]] during the final verse and jokingly warns a camera man that [[PrisonRape he's in the wrong place to bend over.]]
* "Oney", which is about a man preparing for his retirement; those plans include sending a final message to the tyrant supervisor who tormented him over the years.
