Run a remote ruby script locally.

If you ever want to try a ruby script without downloading it you can do it like this:

ruby -e "$(curl -fsSL https://raw.github.com/gist/3862719/bb2a7a18f3dc4d95cfa77d637317e296a114eak1/some_script.rb)"

I know this is not rocket science but i want to have this line handy.
