Simone Biles is one of the best athletes in Olympic history. One thing she is not, though, is tall.

The 19-year-old gymnast stands at just 4-foot-8, but her incredible five-medal showing at the 2016 Olympics in Rio De Janeiro have made her larger than life. On Wednesday, her tour around the country brought her to Chicago, where she stopped by a Bulls practice.

Most NBA players, of course, are quite large. So, when Biles held the size-20 shoe of Bulls center Robin Lopez, the resulting photo was nothing short of ridiculous.

That wasn’t the only mind-bending photo Biles took with the Bulls. Here’s the 19-year-old with 6-foot-9 forward Cristiano Felicio:

And here she is with Bulls stars Dwyane Wade and Jimmy Butler and head coach Fred Hoiberg:

Biles’ tour of Chicago didn’t stop with the Bulls, as she also attended the Chicago Blackhawks’ season opener against the St. Louis Blues and even posed with members of the DePauw women’s basketball team at the airport.

That’s Blackhawks star Patrick Kane on the right, who somehow still towers over Biles despite standing at just 5-foot-10.

In all, it was a pretty cool day for Biles, but we’re still waiting for the moment she meets Yao Ming.
