Weirdly (for me!), it's been sweeping the nation. Teens have been throwing themselves out of moving cars to do a dance. It's an internet craze called the 'Kiki Challenge'.
Now a Bettendorf teen has ended up in an Iowa City ICU and frankly she's lucky it wasn't worse.
18-year-old Anna Worden has been dancing since she was very little.
"We were over by the round-about, and I thought it would be a fun idea to do the Kiki Challenge," she told WQAD.
"I tried, and the last thing I remember was opening the door. So apparently I got out and tripped and fell and hit my head," she added.
Anna had a fractured skull, blood clots in her ear and bleeding in her brain.
This teen who could dance like an angel is now having to learn to walk again.
