A new dispatcher at work was trying to handle an inquiry that grew increasingly complex. She finally said, "I'm new here, I'm going to let [another dispatcher on duty] handle this."
The enquirer accepted the deferral and asked, "While I'm waiting, could you get me a bucket of propwash?"
I'm proud of her for the way she rolled an eye at him and said levelly, "I'm not that new."
A 'bucket of propwash' is one of those joke requests used to get laughs at the expense of the uninitiated, like a left handed monkey wrench, or a hundred feet of shoreline. I never sent anyone on one of those fool's errands. Newcomers usually come up with enough crazy mistakes of their own, without my help.
