Plug ‘n play keychains are here! Pick Pong, Asteroids, or Centipede! Pong also comes w/ Breakout & Warlords! Asteroids has Millipede & Centipede includes Yar’s Revenge! Comes with 6’ cord w/ RCA jacks to plug in TV!! Uses 3 AAA batteries, not included. Each measure approx. 1.5”x2”x1.5”

They're $15 each and you can pick them up here. They're cool and all, but you'll always going to have to carry around the RCA jacks and batteries. Then again, you can be like all of the cool kids and wear cord as a belt. [Via: Ubber Review]
