Here are some one liners...
The Insanity Defense: Denied... Mostly -- It is declared illegal to claim insanity to protect you from prosecution if you were sane at the time of the crime. I also talk about rules of evidence and jury nullification.
My Name is Diego Almagro. You Killed My Father. Prepare to Die -- Revenge is a dish best served cold so at dinner, Fernando Pizarro is attacked and killed by Diego, the son of the man Pizarro had executed. I also talk about promises made and not kept and how the sons come back to haunt us.
I Did Not Have Sex With That Woman! -- It becomes illegal to have sex with the Queen of England and not report it. (Apparently the King is an exception.) I also talk about Bill Clinton and the famous "I did not have sexual relations..." lie.
