Santa Claus is coming to UNIX (one for the geeks)

This is the original lyrics of "Santa Claus is coming to town": http://www.azlyrics.com/lyrics/lonestar/santaclausiscomintotown.html

And this is the UNIX version:

better !pout !cry
better watchout
lpr why
santa claus < north pole > town

cat /etc/passwd > list
ncheck list
ncheck list
cat list | grep naughty > nogiftlist
cat list | grep nice > giftlist
santa claus < north pole > town

who | grep sleeping
who | grep awake
who | egrep 'bad|good'
for (goodness sake) {
be good
}
