This video is a bit different, because the video is aimed directly at their victim (read: subject), and he smiles at it once it starts. In addition, he has already had his two videos, but it becomes apparent who the video is actually about once he starts.
The well known voice says "Okay, go!" and then Thor begins to speak. "Okay so, I really like snakes, everyone knows that, so one day when we were children I saw a small little snake and I went to pick it up, because, you know, I like snakes, but then suddenly the snake transformed into my brother and he went 'Bwah, its me!" And he stabbed me." It was amusing to watch his facial reactions as he told his story, going from a broad smile to almost childish excitement to sadness so quickly.
Then Spiderman's voice came back in and he said, "Okay, now do it like I showed you." He took a few steps back so as to get the god's whole body in the frame. The camera shook up and down like it nodded and then Thor gave a big grin to the camera and gave it a big thumbs up as he proudly declared "Fucking mint!"
