Michael Goldfarb, a surgeon, waiting for his car to be repaired, walked over to observe the process. After they introduced themselves, they began talking, and the talk turned to their lines of work.
"You know, doctor," said the architect, "I sometimes believe this type of work is as complicated as the work we do."
"Perhaps," Dr. Goldfarb replied. "But let's see him do it while the engine is running."
