A woman was in court for killing her husband. She said she wasn't guilty and that she dearly missed him. In the closing statement, the woman's lawyer stands up and says, "Her husband was just missing. Everyone look at the doors. He's going to walk through them in about 30 seconds."
The entire jury stares at the doors waiting for waiting for this woman's husband to walk through the doors. The lawyer and the woman stare at the jury.
The lawyer concludes by saying, "See! If you were so sure she killed her husband, you wouldn't be watching that door!"
The jury immediately gave a guilty verdict. Why?
