This is a perfect example of just how crazy (and amusing) Sheldon can be. If it hadn't been funny enough when Sheldon arrived at the cinema to join Leonard on his date, having overstepped many boundaries by rifling through Leonard's computer to do so, he then tries to find the now-group better seats. Of course, there's nothing unusual about this but his reasoning and how he chooses to do it is hilarious. He makes his way around the cinema, selecting seats and calling out strange noises. It's safe to say that the other people in the cinema look a little bemused but Leonard's date doesn't run for the hills at his crazy friend's behaviour. Sheldon finally finds the 'sweet spot' exactly where Leonard was already sitting. Of course, Sheldon can't just sit NEXT to the sweet spot, but Leonard refuses to move. So he cranes his neck, sitting with his head above Leonard's shoulder and a goofy smile stretched across his face.
