Angry, ineffectual parent: You haven't learned your lesson son. You remember last time you messed up and got away with a bunch of stuff (stuff you made lot of money off of)?
Kid: (Smirking) yeah
Parent: You remember I almost punished you real bad?
Kid: (Smirking) yeah
Parent: Well, you fuck up again. I might almost punish you even worse. I might almost make you really sore. You understand?
Kid: (Smirking even more) yeah, I understand.
