From a 1998 rec.humor.funny post, the nerd Xmas carol:
better !pout !cry
better watchout
lpr why
santa claus
cat /etc/passwd >list
ncheck list
ncheck list
cat list | grep naughty >nogiftlist
cat list | grep nice >giftlist
santa claus
who | grep sleeping
who | grep awake
who | grep bad || good
for (goodness sake) {
be good
}
