69

 69 adj. Large quantity. Usage: Exclusive to MIT-AI. "Go away, I
       have 69 things to do to DDT before worrying about fixing the bug in
       the phase of the moon output routine..." [Note: Actually, any
       number less than 100 but large enough to have no obvious magic
       properties will be recognized as a "large number". There is
       no denying that "69" is the local favorite. I don't know
       whether its origins are related to the obscene interpretation, but I
       do know that 69 decimal = 105 octal, and 69 hexadecimal = 105 decimal,
       which is a nice property. - GLS]
