Which of the following is illegal?

(A) = Saying "hi" to someone politely.

(B) = Cooking Mash potatoes and accidentally made it ugly.

(C) = Swinging a bat around in public for no reason.

(D) = Making fun of the clouds.

(E) = Carrying a Firearm with a License for it.

(F) = Killing someone for self-defense purposes.

(There is only one answer that is illegal and could get your bat taken away and fine, and maybe incarceration (Arrest), and this is an example called disorderly conduct.)
