Andy Samberg - Doesn't think you should mess with McBride

"Why is Danny McBride (who plays Rico) blasting Bill Hader (Dave) in the face with a hose? Simple. "You know, you don't want to say the wrong thing to McBride," Samberg cautions. "He's a rough-and-tumble mother*." As for working with fellow SNL cast member Hader, Samberg says, "There's a lot of family going on set.""
