Just found some good Catholic humor online: Theology 911 Final Exam. My favorite question:
St. Thomas Aquinas and St. Augustine of Hippo decide to rob a bank. The note to the teller is 1,200 pages long, not counting footnotes, complete with a promise of damnation if the teller does not accept immediate Baptism. In the middle of the heist, they engage in an extended debate as to whether or not the money really exists. Are they committing a mortal or a venial sin?
