Author Joe Sacco promises that, in the vein of underground comix like ZAP or Weirdo, "Bumf will go where it needs to go, and do what it needs to do." Though Sacco is world-famous for his serious, journalistic books like Palestine, Safe Area Gorazde, and Footnotes in Gaza, Bumf promises to echo back to his earlier days as a satirist and underground cartoonist. Bumf is a project that Sacco has been working on in between larger projects like Footnotes in Gaza, indulging his love of satire and cartooning. Often puerile, disgusting, and beyond redemption, Sacco apologizes in advance, saying he couldn't help himself. "They expect better things from me. They’ll never put me on a stamp now."
