In this deleted scene found on EW's site, where they have the exclusive deleted clip from Avengers, Mark Ruffalo has woken up after he Hulked out, plummeted from the sky, crashed through a building and woke up naked in a pile of rubble.
“Are you a big guy that gets all little, or a little guy that sometimes blows up large?” Harry Dean Stanton's security guard asks Ruffalo after he's buttoned up his shirt. Otherwise, it would have taken on all other sorts of connotations. It gets all existential from there.
Watch the clip on EW's site.
