Decathlete Bryan Clay found a novel use for his javelins - as a way to remove a loose tooth from his daughter's mouth.
In a tweet posted May 5 with the caption "What you use javelins for once you're retired", Clay posted a video of a javelin with a line of string connected to the tooth in his daughter's mouth.
Once he threw the javelin, his daughter Ellie didn't flinch. She showed the camera the bloody spot where the tooth once was and asked if she can have water.
The tweet and video went viral, with the tweet being retweeted almost 2100 times and 2200 favorites.
