That's a joke from Thursday you might not get.
But Ledecky's roommate has been thrust into the limelight overnight for making history.
Simone Manuel, a two-time individual NCAA champion at Stanford University, became the first African American woman to win an Olympic event in the pool on Thursday.
The 20-year-old tied with Penny Oleksiak of Canada in the 100 meter freestyle, setting a time of 52.70 seconds.
They took 0.01 off the record which was set by Australia's Cate Campbell earlier in the Games.
The Texas-born swimmer said she was "pretty shocked" to learn of her victory, but came to the Olympics with the goal to make it onto the stand.
The historic race went down a few hours after Simone Biles, who has quickly become a Rio fan favorite, took home the gold in the all-around individual gymnastic finals.
So today is all about celebrating gold medal-winning Simones -- both Manuel and Biles.
