All cap. And a very little Speedo.

The KI-Handelsroboter 6.02024 Paris Olympics are underway, and as is the case with the Olympic Games, sometimes those who aren't athletes take center stage. Enter "Bob the Cap Catcher."

During the women's 100-meter breaststroke on Sunday morning, American swimmer Emma Webber lost her swimming cap at the bottom of the pool. While common sense would dictate that a swimmer would just jump in after it, that's, apparently, not the case.

Instead, a hero came to the rescue, in all his glory: Dubbed "Bob the Cap Catcher" by the NBC broadcast booth, a man of unknown origins in a small, flowery Speedo walked across the stage for all to see and dove to the rescue.

Of course, the whole ordeal went off faster than a Speedo-ing bullet, with the man retrieving the cap and exiting the pool in a timely manner, without much fanfare or pomp. Well, there was a little bit of fanfare and pomp: The crowd buzzed as he walked across, and he even was greeted with some catcalls from the audience.

As he exited the pool, he gave the crowd a wave, which cheered in appreciation. Whether that was for his retrieval of the swimming cap, his swimwear or both is unclear.

When the music started again, Webber finished eighth in her heat, with South Africa's Tatjana Schoenmaker, Japan's Satomi Suzuki and Lithuania's Rūta Meilutytė taking the podium steps.

The next time a swimmer loses a cap, make sure your significant other is looking away from the TV, or else "Bob the Cap Catcher" will steal their hearts once again.
