House of Fun #[0]

Most of the contents of this comic were originally intended for the 12th issue of Dork (Slave Labor, 1993 Series), but they were instead printed in Dark Horse Presents (Dark Horse, 2011 Series) #10-12, and then collected here. The number 0 does not appear in the indicia or on the cover, but the author's introduction does refer to this as issue #0.
