G-Friend and the 'Infinity Challenge' crew teamed up to complete ridiculous missions on a roller coaster on the August 13th Los Angeles special of the variety show.

If riding extremely scary roller coasters wasn't enough, the girls and cast members were tasked with things like eating and singing during the ride. Sowon and Park Myung Soo had to sing IU's "Nagging" as a duet on the roller coaster, but they screamed into the mic instead.
G-Friend's Eunha probably had it the worst as she was given the challenge to eat a meal on the ride alongside Park Myung Soo, which proved to be incredibly messy.
Still, the girls of G-Friend were great sports!
