Ancient nerd legend has it that anyone in possession of these three things will have REAL ULTIMATE POWER.

Its a pin. Its a synapse neuron. Sweet.

From now on all my eating and drinking implements will display the chemical structure of their contents.

Pong. Batteries. Shirt. Need I say more?
Those last two came from the ever-awesome ThinkGeek, but the neuron pin came from an amazing site aptly-named Neuromart. Neuromart contains items of such phenomenal nerditude that I died a little inside that I didn’t think of it first. Neuromart, I salute you.
Hat tips to Charlie and darkman.
