Not sure what it is ... but I felt like I was kid again when he hit Thor and wrecked up Loki.BTW, Hulk fans are a crazy bunch. I sat next to a couple when I saw the film today. The sheer giddiness they display when Hulk smashes shit is a sight to behold. When Hulk beats the shit out of Loki, I thought they were going to jizz in their pants.
I'm 36, an I really can't remember the last time I laughed with such wide-eyed, childish glee at a movie scene.
