Former Olympic Gold Medalist and World Champion decathlete Bryan Clay posted this video on his Twitter account of how he's using the javelin nowadays.

The 2008 Olympic Champion took his 5-year-old daughter Ellie to the park after she had been wiggling her loose tooth all day, according to his Twitter account. Clay attached a string of floss to the javelin and her tooth and let the jav fly!

Two-time Olympic 100m hurdler Lolo Jones may also require Clay's dental expertise.
