Once a girl swallowed a magic pebble on Christmas Eve. Her mom had to call the doctor to find out whether she should throw it up right now or let it take a leisurely trip down and out. Down and out was the winner. A few days later the mom was exceedingly happy to fish a glowing blue orb out of the commodious sea.
One year later a girl suddenly stood up and ran away from the traditional Christmas Eve chili dinner. Time was of the essence and the door leading to the commodious sea was closed. A chili volcano erupted. The dad did not take pleasure in the aftermath. The girl declined all offers of chili for at least a year. It's possible the dad did too.
Nothing unusual happened on Christmas Eve in the following years. The mom and the dad were relieved.
