Three citizens were going through an exam to become agents of the FBI. Their instructor handed the first guy a gun in a room with his wife and said he had to shoot her. He walked out in shame and said he couldn't do it. The second guy had the same scenario. He put the gun up, but couldn't pull the trigger, so he walked out in shame. The third guy was put in the same scenario. He walked out and told the instructor, "The gun wasn't loaded, I had to strangle the bitch."

What is the difference between a feminist and a vegetarian? A vegetarian doesn't eat meat for moral, religious, or health reasons. However, a feminist doesn't act like a bitch for moral, religious, or health reasons.
