 Haake explains that "Catch Thirtythree"'s cover, title and lyrics deal with "the paradoxes/negations/contradictions of life and death (as we see it in our finest moments of unrestrained metaphoric interpretation)".The main theme of "obZen" is "human evil", according to Haake.The title is a play on the words "obscene" and "Zen"; in addition, "ob" means "anti" in Latin.
