Me: "Hey MJ. Listen to this. 'Chemicals were identified as cancer-causing agents in the latter part of the eighteenth centery when Percival Potts noted than chimney sweeps had a higher incidence of cancer of the scrotum associated with exposure to soot residue in chimnesys.'"
MJ: "Okay.........why cancer of the scrotum?"
Me: "I imagine it had something to do with them attaching brushes to their crotch and humping the chimney clean.......try not to laugh about that during the test. They will think we are cheating."
