B.O.B

A United Airlines plane flying from Sydney to Los Angeles was forced to make an emergency landing 90 minutes into its flight.  The pilot decided to turn the plane back to Sydney after a sick bag with the letters B.O.B on it was found in the toilet. 

Channel News Asia reported:

Transport Minister John Anderson said the pilot feared the letters stood for "bomb on board" but acknowledged it was a common acronym among air crew for "bastardbest on board", used to rate the best looking passenger on a flight.

Oh.  If you are a UOB employee, make sure you don't bring any baggage with your company's name on it when you are taking a flight.  :)
