Happy didn't really like how that last part sounded like a question because he didn't know. All he knew was that the Hulk had gone on more than one rampage and he'd probably thought he had the green guy under control then, too. But these weren't things you said to the dude who became the Hulk. "Yeah?" was all he said and started taking the hot dogs off the grill and plating them. "Well that's good, then."
