Looking to nerd up your plain old everyday high-fives? Try the Sci-Five. It's perfect for celebrating all kinds of geeky conquests with your friends, like snagging the last copy of the latest Maxim at the newsstand, or getting Simon Pegg's autograph at Comic-Con. It's easy to do. As pictured in the T-shirt above, just grab a friend, make a Spock Prime-patented Vulcan salute with your hands and slap away. (Also recommended for first contact situations.)
This great shirt comes to us from the good folks at TopatoCo. Feel free to point us to more geeky goods in the comments.
