The comedian was accompanied by fellow 'Infinity Challenge' member Yoo Jae Suk and the filming crew of 'Infinity Challenge', clearly in the process of carrying out a mission for the show. 

But what kind of mission made Park Myung Soo come riding his bicycle out into the Seoul streets with nothing but his leopard-print underwear?! The combination of his leopard-print underwear, gloves, sneakers, and heart-stickers covering his chest caused quite the stir among onlookers!

Although Park Myung Soo's sight was enough to steer the attention away from Yoo Jae Suk, the MC himself was also decked in what seems like a retro, patchwork outfit. 

One netizen who uploaded a photo commented, "I thought I took a picture of a crazy person but it turned out to be Park Myung Soo." 

You'll have to tune into MBC's 'Infinity Challenge' to find out the whole story!
