If you are outside while wearing the 100% polyester Star Trek Insignia Green Running Shirt you'll probably inspire the Vulcans to arrive and cause the events of 'First Contact'. The Vulcans were getting bored waiting for us to develop warp-drive technology and seeing how we are constantly sidetracked by kitten videos decided that somebody wearing the durable and lightweight Star Trek Insignia Green Running Shirt would be the next best thing! That makes enough sense, right?
