The lights are on
What was the strangest or funniest achievement you've ever unlocked? Mine would have to be in Half Life 2 Episode Two. The achievement is called Little Rocket Man and in order to unlock the achievement you must take a garden gnome that is under a bench at the beginning of the game and carry him with you and stick him in the rocket at the end of the game.
I think getting an achievement in Black Flag for petting five dogs is hella random.
