Best: The tent scene (Eclipse)
The ongoing tension and hatred between Edward and Jacob gets a humourous respite in Eclipse when the two join forces to keep Bella safe. With Victoria on the hunt with her newborn vampire army, the two rivals for Bella's affections hole up in a tent in the mountains. With Bella freezing, Jacob helpfully doffs his shirt (again) to snuggle with her and keep her warm, given that Edward, being technically dead, cannot. "Can you at least attempt to control your thoughts?" Edward asks Jacob as he cuddles the vegetarian vamp's intended.
