Remember back in November when EXO's Suho surprised reporters and made fans laugh with his bizarre actions at the airport? The leader suddenly rolled on the ground the moment he got off the van, and also made heart signs with his arms and more. Many assumed it was a dare or a penalty. Well, the full story behind the humorous incident has been finally revealed. 

On the January 22 airing of 'Travel Around The World On EXO's Ladder 2,' it's revealed that Kai suggested they do something when they arrive at the airport. The members agreed and Suho ended up getting picked in the random ladder game. 

Suho rolled on the ground and reenacted Rambo as promised while his members laughed away. Check out the full clips from the episode below.
