If you like to partake in adult beverages, odds are you have some shot glasses around the house. If you are a geek that likes drinking games, ThinkGeek has the perfect shot glasses for you. They are called the Build-on Brick Shot Glasses.
Each shot glass has those little round LEGO-style bumps that let you build right on the surface of the cup. No bricks are included, you only get the glasses. I can see these being used for some interesting drinking games.
You could have a contest to see who can build the wildest shot glass creation that you can still drink from without spilling. On the other hand, maybe the goal is to make your opponent spill their shot by adding pieces to their glass.
Whatever you get up to, these glasses are available now for $19.99(USD) for a set of four. You get yellow, white, blue, and red glasses. Snap together some cash and head to ThinkGeek to order a set.
