You know what's fun? Rollercoasters. You know what's even more fun? Convincing your friends to ride with you and, just as you're about to board, watching their faces drain of color in their moment of regret. Ahhh yes. Your fear. I smell it.

SHINee

The ever entertaining SHINee members show off an array of reactions with Jonghyun tearing, Taemin straight-facing, Onew randomly singing the Japanese version of "Lucifer" (a rollercoaster is a great place to warm up your vocals after all), and Minho genuinely having a good time. Oh, and then there's Key: "OH MY GAD."

Big Bang

Big Bang has a right to be scared for this one. Check out how steep that rollercoaster is! And what's even crazier--the drop curves inward. While all of the Big Bang members are a bit rattled by the ride, T.O.P's blue hair majestically flapping in the wind coupled with "D-LITE" Daesung's not-so-delighted face is what makes this video.

Daesung: "I can't."  

Super Junior-M

In a huge group like Super Junior, you'd think it'd take a while to identify the scaredycat, but he eventually shows himself in the form of Ryeowook. In a rollercoaster that goes back and forth Viking-style, Ryeowook can be seen scrunching his face and squeezing his eyes shut throughout the whole ride. Sungmin, on the other hand, takes it like a champ. He even rides the ride three times, flashing a peace sign with a stone face for laughs. 

Bonus: Check out this clip of Super Junior using a rollercoaster reaction video as a transition sequence for their concert! The cute cartoonifications of their otherwise mortified faces are a nice touch.

Jiyeon and Wooyoung

Once upon a time, a cute 'dino', T-ara's Jiyeon frollicked towards a rollercoaster expecting to have a good time. What follows? The hilarity that is her sudden dread and random bursts of screaming, leaving 2PM's Wooyoung baffled more by her mood swing than the ride itself.

WINNER

WINNER's Lee Seung Hoon reveals himself to have the girliest scream of all as he squeals "OPPA!!" in the clip above at 0:45. That's right, "Oppa*". Boy is so scared out of his mind that he seems to have forgotten his own gender. His other frantic comments are equally funny as he shouts, "I CAN'T SEE ANYTHING," and, "WHY IS THIS RIDE SO LONG."

Meanwhile loner Nam Tae Hyun has the saddest Merry-Go-Round ride ever, as he quietly takes solo selfies and puts that #foreveralone tag to use.

*Note: In the Korean language, only girls call older brothers/male friends "oppas" while boys call them "hyungs." 

Ailee and Leessang's Gary

Ailee shows that she's talented both on stage and on a rollercoaster as she belts to the world "I Will Show You" on a coaster creaking uphill towards her doom. Of course, even the best of singers can't keep it up for long when faced with crazy drops, but hey, at least she hit that high note. Possibly way higher than she meant to.

SHINHWA

Oh my goodness, it's young, pre-30s SHINHWA! Feel that amazement, wonder, and nostalgia burn as you watch SHINHWA youngsters tilt their heads cutely back and forth. The funny part, of course, starts after the first drop, when the SHINHWA members attempt their challenge to drink their food-colored water from their bottles.

The challenge does not go so smoothly as Shin Hye Sung suffers from Eric's bottle sprays and Jun Jin gets water up his nose. The announcer only has eyes for one member, however, as he states at the end, "From the beginning 'til the end, I've only been watching Dongwan's face." For good reason, too.

"Well, this is nice."

BONUS: Running Man

While Lee Kwang Soo looks like a spastic derp as usual, at some points, Ji Suk Jin looks as if he's at death's door. Meanwhile the wide-eyed cutie, Ji Chang Wook, who y'all were probably eyeing, is unable to contain himself either as the 27-year-old screams, "MOMMY," towards the end. Poor babies.
