BTS' Golden maknae Jeon Jung-kook, fondly known as Jungkook or JK, turns 27 today. Despite serving in the South Korean military, Jungkook is making noise for two of his projects - one is the ongoing travel documentary I Am Sure!?, co-featuring his BTS brother Park Ji-min aka Jimin, and the other is his upcoming documentary, I Am Still. In the five episodes from Are You Sure!?, Jungkook has shown us peak JK behaviour too often, and what could be better than revisiting them today? So, here are some top moments from the show, streaming on Disney+Hotstar, where the youngest BTS member showed us peak JK behaviour...

Losing Jimin for cheese

Jimin joined Jungkook at the supermarket, and while Jimin was talking, Jungkook went his way. On one hand, Jimin was trying to find Jungkook, and at the other, Jungkook was searching for cheese. It is to be noted that initially JK had sold Jin for an ice-cream, so this makes it peak JK behaviour.

Watching crabs fight in the middle of shopping

Losing sight of what he initially came for, Jungkook got intrigued by crabs fighting. By this point, Jimin and Jungkook met, and Jungkook invited Jimin to watch the fight. Of course, JK got a winner crab and finally moved on doing what he initially came to the supermarket for.

Not just that, Jungkook actually came to the supermarket the second time to buy a scrub (while Jimin was ill), and ended up buying a snack he wanted to try, over the scrub.

Falling asleep in the chair after eating

Are You Sure!? is all about Jungkook eating heartily. His reactions are always epic, and the first time when he and Jimin came together, Jungkook, just like a baby, fell asleep on the chair after feeling satisfied through good food.

Building a rock tower to pray for Jimin's health

Needless to say that BTS members hold the highest place in Jungkook's heart. He cannot see any of his members in pain. In the past, JK has cried every time his member broke into tears. This time, while taking care of Jimin (after punching his nose in sleep), Jungkook searched for and built a rock tower to pray that Jimin's health shows improvement so that they could have a good day ahead.

Riding a bike and pretending to be mafia

After Taehyung, fondly known as V, joined them, Jungkook brought out his biker mode. He hopped onto the elegant two-wheeler and left many breathless with his mere presence. If that wasn't enough, JK pretended to be mafia with Jimin and V waiting in the car. Jungkook drove the bike towards them and gave Jimin-V a deathstare. The duo said they're just normal human beings and they aren't who he's looking for. Cussing under his breath, JK moved on.

Waking up and rolling on the floor to sleep

Jungkook woke up, only to fall down, roll on the floor and sleep. That is something only JK can manage to do.

Mimicking another unexpectedly

In the past, Jungkook has mimicked all of his BTS members, and even Suga (Min Yoon-gi)'s father or an elder interviewee who called RM Rrrap Monsterr. This time, JK mimicked an influencer who accused his fans for making him fat. He also sprinkled salt like a popular personality on the show in the most recent episode.

After Are You Sure!?, Jungkook is now awaiting the release of his documentary, I Am Still. The same will be out in theatres on September 18, two days before BTS leader RM (Kim Nam-joon)'s birthday.
