"Insert coin": The game Arcade edition! Just insert the money and leave right away, saves up to several hours of stressing gameplay! Its not like you are getting the money back you know! Moral: Reminds me of a arcade hall I saw in Chile once, only one cabinet had a screen, but no working "game tokens" receiver :P, they also had a ping pong board with no ball, no idea why the hell the place was even open at all XP
