Ignore the sarcastic pricks. It's from Portal 2. The yellow robot keeps commenting on how he wants to go to space, and when you *spoilers* to defeat *spoilers*, it ends up orbiting the moon. In a last scene before the absolute end, it appears again, rambling on about how excited he is to be in space. You can find a video of it on Youtube if you're too lazy to play through the whole game.
Last time that happened, a naked Gnome that was on Mescaline awoke in the valley of honor, drank a Venti Non-fat, organic chocolate brownie frappuchino, extra hot with foam and whipped cream, upside-down, double-blended. And blasted an Ogre into oblivion with a Caffine/Mescaline-fueled blast of energy that encircled the planet.
