Subject: Your Favorite One Liner

Give out your favorite one liner, what it does, and when you use it.

For me:

puts ARGV[rand(ARGV.size)]

It randomly prints one of the command line options passed to it.  I
typically use it to make a decision when I have no preference (or have
equal distaste) for my available options.

For instance

ruby -e "puts ARGV[rand(ARGVsize)]" "shoot self in head" "use Java"
