Ask for two professions that have nothing to do with one another. Someone in the scene plays a character that is now doing the second job. HOW the job is done is affected by the first job. Ex: Vet/Auto Mechanic. The mechanic, might check a car for fleas, neuter a van, or put a milk-bone in the gas tank.
