Basically

Two men stand in a dimly lit room, one in the foreground looking toward the camera with a serious expression while the other, in the background, adjusts his collar; the man in the background's head is replaced by a floating, detached head that moves slightly. The scene cuts to a man and a woman standing together in a warmly lit interior with string lights, both looking off-camera with expressions of surprise; the man's eyes are replaced with pixelated sunglasses and the text "surprise rat" appears on screen.
