Boredom is a dreadful thing, so you should always find ways to get rid of it. Thankfully, Think Geek is always around to rescue geeks from being sucked into a bland dark place in their mind. Now you can spend your days strumming on a fake guitar on your shirt. It has all the major chords and plays them out loud for all the world to hear. Whether they like it or not.
The major chords that you have will allow for you to play a great deal of classic rock songs. That or you could just randomly hit buttons and make everyone around you completely annoyed. There is a mini amp that comes with the shirt. It has a tone nob that allows for you to turn the volume of the guitar up and down. The amp can be clipped to your belt. You can purchase the shirt and amp set for $29.99 from ThinkGeek.
