Did you know about the -o option of the fortune program?  It makes a
selection from a set of offensive and/or obscene fortunes.  Why not
try it, and see how offended you are?  The -a ("all") option will
select a fortune at random from either the offensive or inoffensive
set, and it is suggested that "fortune -a" is the command that you
should have in your .profile or .cshrc. file.
