What you use javelin for once you're retired...

A retired US Olympian Bryan Clay pulled out his daughter's tooth by tying it to a javelin and throwing it into the air.

The video, which has gone viral over internet, shows Clay, who won gold in the decathlon event at the 2008 Olympics, launching the javelin and his daughter's tooth flies out of her mouth.

"She was jumping in the house all day asking me to do it," Clay said. "She was excited about it. She kept wiggling the tooth all day." 

Ellie however turned out to be a brave girl as she didn't cry one bit, and only asked for a glass of water to wash her mouth.
