Olympic lifeguard 'Bob the Cap Catcher' becomes internet sensation after diving in to save Team USA star's swim cap in tiny speedo

Not all heroes wear capes, as one speedo-wearing Olympic lifeguard proved in Paris over the weekend.

During Sunday's preliminary women's 100-meter breaststroke race, Team USA swimmer Emma Weber suffered a slight mishap when her swim cap came off and sunk to the bottom of the pool.

Despite Weber likely having a second cap on her head, as NBC commentators pointed out in the network's live broadcast, an unidentified lifeguard wearing tiny floral speedos was soon on hand to save the day.

The lifeguard, dubbed 'Bob the Cap Catcher' by fans online, dove to the bottom of the nearly 10-foot pool and rescued the swim cap after the preliminary race was briefly brought to a halt.

And as he exited the pool with the cap in hand, he held it aloft in triumph while waving to an adoring crowd.

'That was an Olympic moment,' one of the commentators laughed. 

Fans also rushed to social media to heap praise on 'Bob the Cap Catcher' after his viral moment in Paris.

One wrote on X: 'He’s an icon he’s a legend he is the moment'.

Another commented: 'y'all may not like it but this is peak male performance'.

'Been waiting his whole life for this moment,' said a third.

A fourth put: 'Bob kept the Olympics from falling apart. Way to go Bob!'

While one simply concluded: 'This should be a sport too'.

Olympic reporter Devin Heroux confirmed that the mystery lifeguard wishes to remain anonymous after his heroics.

'I’ve confirmed who jumped into the water to get the swimming cap. It was a lifeguard in a speedo,' Heroux said.

'He does not want to be named. Not all heroes wear capes. Or much at all.'
