The Parable of the Bus

Josh writes:

Nice work on this week's cartoon! Incisive and funny. Did you base the cartoon off of a classic parable or was this an original formulation? In either case i think it's a great comic, i'd just be interested if you drew on a traditional parable.

I've lived in New York a long time. The bus is often late, forcing one into the dilemma described in the cartoon, and I've often used that analogy to attack those who say we have to stay in Iraq to "get the job done." Why throw good lives after bad? This thing is no more winnable now than before...and that's being optimistic. Hell, Bush is so fucking incompetent that, at this rate, we'll be living under Iraqi occupation before long.
