The Official MBA Handbook on the use of sunlamps:
    Use a sunlamp only on weekends. That way, if the office wise guy
    remarks on the sudden appearance of your tan, you can fabricate
    some story about a sun-stroked weekend at some island Shangri-La
    like Caneel Bay. Nothing is more transparent than leaving the
    office at 11:45 on a Tuesday night, only to return an Aztec sun
    god at 8:15 the next morning.
