Who: Lolo Jones, Olympic track and field hurdler/bobsled team member
The fail: Making fun of a paycheck that was sent to her for seven months' worth of work with the U.S. bobsled team in a Vine video
When you're endorsed by the likes of McDonalds, Red Bull, and Asics, you can afford to make jokes about $741 checks being too small to pay your rent. The only problem is that you have bobsled teammates who live for that $741 check and probably aren't going to be too happy with you. Have fun at your next practice!
