I am a huge 1N2D (Two Days, One Night) fan and basically, Kim Jong Min is my K-variety animal.
For two decades, he decided to be this funny buffoon and whether he's staging this for his image, most of his antics are extremely effective.
Such is the case here - when he tries to spell "too much information". Aside from being ultra-confident, he has to annoy everyone first... which makes his comeuppance funny as hell.
At a time when Han Ga-in and Youn Jung-hoon are supposed to be the main characters of the show, Jong Min's brain cells can't allow the couple to just stand out without his awesome nonsense.
