"What were you thinkin' about doin'?" Yondu just sits down, elbows on his knees. He's, sadly, not much of a prankster himself but he has seen his crew go completely insane chasing each other down because one asshat pulled something on another dipshit and before he knew it people would be throwing down money on whether the situation would end up in broken bones or hugging and crying (which wasn't that uncommon with his better boys).
