To plug Ruby directly into your brain, take three short breaths, mutter a prayer to Matz, and then follow these instructions:

Prerequisites: Mac OS X Panther or greater and Quicksilver

1. Download this humble Applescript

   \#<using terms from application "Quicksilver"
       on process text t
           do shell script "ruby -00 -e '" & t & "'"
       end process text
   end using terms from

2. Unzip the script and copy it to `~/Library/Application Support/Quicksilver/Actions/`
3. Restart Quicksilver

Once you’ve plugged in, Ruby is just a blink away:

1. Invoke Quicksilver (`CTRL-Space`)
2. Type a period (`.`) followed by your one-line stroke of genius, such as:

   \#<\[ "in", "me", "plug" \].reverse_each {|x| print x.upcase, " "
   }

3. Press `TAB`
4. Type until `ruby` is displayed in the second pane
5. Press `Return`

The results of your Ruby one-liner (‘PLUG ME IN’ in this case) are placed back into the first pane of Quicksilver for your digestion.

Thanks to bsg for the inspiration.
