The only rule is to make sentence and turn are sentences into a story.
I'll start.


One day a man was at a football game and got hit by a football.

(now you go.)

The man starts crying and screams "mommy, mommy, I need a Band-Aid."

Instead, his mom gives him a clown.

And starts screaming...

The stadium turned into a big hot dog.

Then ketchup and mustard was dumped all over it.

The ketchup and mustard began crawling and bubbling in the hot sun...

They started to eat it, and the liked it, they ate and ate and ate and ate and ate and ate, then then they were done.

(a lot, huh?)

But then they saw a GIANT teddy bear on the sidewalk alone

They all grabbed it.
