This Star Trek t-shirt features an image of Captain James T. Kirk. The shirt reads Beam Me Up Scotty. When Captain Kirk was on a mission, and wanted to return to the USS Enterprise, he called on chief engineer Scotty to bring him back using the transporter, which would convert Kirk's molecules into energy, then beam them into a chamber, then reconvert them back into Kirk's original pattern. In the Star Trek universe, this has been called the safest way to travel.
