Valentine's Day Massacre

Jack: Well, I will use my sword and if a policeman comes up to me, I will cut him.
Me: But Jack, policemen are good. They protect you.
Jack: Protect me from what?
Me: From the bad guys.
Jack: What bad guys?
Me: Uh...
Dean: You mean like the Joker?
Me: Yeah! Like the Joker.
Jack: Well, if the Joker tries to get me I will cut him with my sword and I will cut his head off. And, even I will cut up his whole body.
Dean: What about his bloooooood?
Jack: Even I will cut him blood because he needs his blood and I will cut it.

Hmmm, maybe they were too young to watch SAW III.
