Alright, I have seen some cool geek T-Shirts before, but this one is takes the cake for me. I love this thing. I mean how cool is it to have a shirt that needs batteries? I would love to walk around with this thing on. How cool would it be for a teacher to just pointing to his shirt and say, "See, the noise level in here is too loud, we need to use our inside voices." If you already bought the Monty Python Horse and you still need another gift for the geek in your life you can’t go wrong with this.
