Can you watch this for four minutes? The end is pretty funny, so I advice you to do so. What happens when Bruce Banner (A.K.A. The Hulk) threatens Loki, God of Mischief? Well...this of course! By the way, this is arguably the funniest scene in the entire film. Oh, and just so I make things clear with this footage... I didn't shoot it. I found it online.
