That was a really creepy episode (that crude humor on the surface with the thinly veiled threat beneath) and I love this gifs from it.

It always amazes me how concentrating on a few seconds of a scene and putting those in a loop often changes my perception of a scene. The last one - I've seen this scene many times but seeing this particular look on John's face again and again leaves a different impression from seeing it just once, fleeting, in the real scene. Hard to explain ...
