This is nerd sniping at the finest. After reading that document I am embarrassed to admit that I now understand how this code is a UNIX `cat` implementation:
lick Trisha's toes ten times
make Clara moan
Until Amy is dominant towards Alicia
Have Mistress torture Brian's ear
If Brian is Trisha's bedtoy
call safeword
Have Brian hogtie Clara
Make slave scream Clara's name
Hints: 'slave' is stdout, and everything after a single quote is ignored. 'lick' is addition, 'moan' and 'scream' are print and println respectively. 'until' is while, and 'call safeword' is break. 'Mistress' is stdin, go read the tutorial for the rest.
Even this is toned down as I could not bring myself to post the original on HN. For instance, in the real tutorial it is not Brian's ear that is tortured...
