Buffy + Giles - season 6. I adore this scene. I love how Giles just starts laughing because it's all so ridiculous. Joss is the master of taking a suspenseful/dramatic scene and turning it on its head.
I really like this poster because the colors make it pop and jump out at you as well as being a unique concept that you almost never see. Also, I love how it's a photo of 3d elements. I just wish the hand wasn't there.
