Don't have a cowbell to cheer at the winter olympics? Have an iPhone? Don't worry! There's an app for that!
Ain't technology great? Now you can cheer on the olympians for less, and not have some useless piece of crap sitting around your attic until 2014.
Cheapest price I saw for a real cowbell: 2.45
Cowbell app: Free! (if you own an iPhone - I don't)
