Members of BTS underwent intensive training before they officially debuted in 2013. Some of them even started with Big Hit Entertainment as early as 2010.

While the specific details of their trainee days remain scarce, the K-pop stars would recall some of it from time to time, especially those that are fond and memorable. Koreaboo recently listed a few of the funniest moments that the seven members shared during the old times.

Speaking to his channel, Brightoon TV, former trainee Jihoon revealed his funny experiences with some of the celebrities. He began with his "string cheese moment" with Jungkook.

He said that he and the rest of BTS would usually go to convenience stores to eat during their breaks. Jungkook once, reportedly, brought string cheese with him at the store.

The cashier, then, recommended for them to microwave it for ten seconds as the cheese would melt and become more delicious. Upon obtaining the advice, Jungkook did not follow the instructions and placed it for 30 seconds.

After a while, Jihoon said that he heard him screaming because all the cheese had melted down. Since then, the youngest member of the group never placed cheese on the microwave again for more than ten seconds.

Jihoon, also, shared his and J-Hope's funny experience with RM. After taking showers, they, reportedly, lied down shirtless to watch television. But, when the internet star lifted his back, the movement created a "fart-like sound," which caused the BTS rapper to burst into laughter.

They, then, decided to recreate the same sound with the use of other body parts. However, their loud laughter woke RM up from his sleep.

The group leader went out of the bedroom and asked them to be "quieter." Although they did apologize, they could not contain their laughter, which woke RM up again.

Apart from those moments, the members of BTS themselves had funny experiences when they first met each other. A separate report from Koreaboo covered the matter, starting with Jungkook and RM.

As it happened, the youngest member of the boy band first met the group leader without his pants. But, Jungkook did not, reportedly, mind as he was "amazed" by RM's thighs.

J-Hope and Suga had a similar encounter back then. When the two rappers met, J-Hope said that his friend was only wearing his underwear when he first entered their dorm. Suga, later on, recalled how tan J-Hope was during their first meeting, deeming him the "tannest person" he ever met.
