Create a breaking news story. This should be fake news. You should create a dialogue and have an AI read it using text to speech. There are several free programs. One possibility is Colossyan.com. Mix in a news jingle to make your story sound legit. You can find some jingles on freesound.org. Be sure to give credit if necessary. 

Be creative, funny, or serious. The choice is yours. Just make it sound realistic.
