LOL the ending of the challenge is very funny!

Once you have Ruby installed, you can use Interactive Ruby by running irb on your system's command line utility.

You really deserve a double-layer cake with double-double frosting and a guy playing one of those guitars that's a double guitar. I mean you finished, you really did! 

No doubt about it, you're a certified red-blooded smartiac!
