Saw this on another forum, try it out. Do it like this.
I'll start with "Tim went to the store."
You then add a sentence in the reply. "Tim went to the store. He saw milk and carrots, so he bought them."
Let's begin!
Jerry was watching TV one day.
"My head has come aflame!" shouted Frank as he suddenly burst into the room, startling Jerry who then quickly jumped to his feet.
"Oranges are the answer!" Jerry said before grabbing his keys and going to the supermarket.
"Don't forget the tooth paste!" Frank yelled at Jerry, who for some reason had stripped off all his clothes in public and walking quite funny.
"Toothpaste...IS the answer !" The Vixen shouted as she wrung a big tube of Crest viciously between her paws , directing the minty-white extrusion at frank's flaming Toupee.
