fioricet According to a recent and unscientific national survey, smiling is something
     everyone should do at least 6 times a day. In an effort to increase the
     national average (the US ranks third among the world's superpowers in
     smiling), Xerox has instructed all personnel to be happy, effervescent, and
     most importantly, to smile. Xerox employees agree, and even feel strongly
     that they can not only meet but surpass the national average... except for
     Tubby Ackerman. But because Tubby does such a fine job of racing around
     parking lots with a large butterfly net retrieving floating IC chips, Xerox
     decided to give him a break. If you see Tubby in a parking lot he may have
     a sheepish grin. This is where the expression, "Service with a slightly
     sheepish grin" comes from.
