A young man fresh out of college gets a job at a factory.
When he arrives he surprised that he is assigned as junior janitor. Shocked he asks for the manager who hired him. “Didn’t you read I have a double major in Social Science and Anthropology”
“Oh” says the man, “ I must have missed that. OK let me explain. Lift the mop up and put in the bucket, then wipe the dirty floor with it.”
