Police justice

The boys like to pretend that they are police officers eating at a Mexican restaurant and that I am the server there. They also like to feed me lines, like this one:

Thing Two: Mommy, say (to me), "If you get that bad guy who's drinking alcohol and kill him, you can play Star Wars Lego Wii."

Bad-guy math

Thing One: What would happen if you have a bad guy robbing a train on a horse and behind him there was another bad guy on a horse?
Me: I don't know.
Thing One: Well, he wouldn't shoot the other guy because they're both bad guys.
Apparently, two bad guys cancel each other out, dangerwise.
