Infinite Challenge Star Jung Hyung Don Breaks 22-Year Silence on Park Myung Soo’s “Mistreatment”

Jung Hyung Don, a longtime star of Korea’s legendary variety series Infinite Challenge, has broken a 22-year silence about a period during the show’s early days that left him feeling intimidated and severely marginalized. In a new conversation posted on YouTube, Jung Hyung Don says Park Myung Soo made him feel “self-conscious” and that, during filming for a high-profile Infinite Challenge segment, he believes he was treated differently from other cast members who suffered injuries. Park Myung Soo later responded on the same topic, acknowledging competitiveness and apologizing if his actions hurt Jung Hyung Don.

A rare backstage confession after more than two decades

According to Jung Hyung Don, his decision to speak up comes with reluctance—he said he generally avoids revisiting the past because it can feel like “selling nostalgia.” Still, he described how, early in his tenure on Infinite Challenge, he felt suppressed by Park Myung Soo’s attitude.

Jung Hyung Don’s account ties the tension to broadcasting rivalries of the era. He explained that Infinite Challenge and KBS variety show Sang Sang Plus were filmed on the same day, and he worked between networks at a time when broadcasters were wary of talent appearing across competitors. In that context, Jung Hyung Don said Park Myung Soo’s discomfort with outsiders made him feel exposed.

“This is my first time saying this in 22 years,” Jung Hyung Don said in the video, describing how the pressure intensified until he briefly considered leaving the show. He added that Yoo Jae Suk and producer Kim Tae Ho ultimately persuaded him to keep going—an intervention he credits with preventing his early departure.

The injury incident that, he says, changed everything

Jung Hyung Don also recounted a second memory he called especially painful: the Infinite Challenge bobsleigh special, one of the program’s most famous stunts. He said he was injured during filming and believed the production team initially failed to take his condition seriously.

In his telling, the cast relocated without noticing his absence, meaning he ended up left behind while others continued. Jung Hyung Don said he wasn’t even immediately aware that people had moved on without him. He later went to the hospital for an examination—where, he claims, doctors were surprised by the extent of his injuries.

Jung Hyung Don said he had served as the fourth brakeman and that the injury involved ligaments in a way that doctors found unusual. “The doctor said it was his first time seeing someone injure both the first and second ligaments,” Jung Hyung Don claimed.

Park Myung Soo’s alleged remarks and an apology

While Jung Hyung Don said he was already angry at the production team, he added that Park Myung Soo’s response struck him the hardest. He alleges that Park Myung Soo treated his injury as less legitimate than those of another performer—specifically pointing to Jun Jin, who he said was also injured and sent to the hospital.

Jung Hyung Don claimed that, despite Jun Jin being transported for medical evaluation, he was not—because Park Myung Soo allegedly told others that he was “putting on a show” and didn’t want to ride. Jung Hyung Don said the remark was edited out of the broadcast, but that Park Myung Soo said it in essentially those terms.

Park Myung Soo did not deny the core of Jung Hyung Don’s account in the follow-up conversation. He described himself as a senior comedian at MBC when the situation occurred, adding that there was a competitive dynamic. Park also issued an apology, saying that if his words or conduct harmed Jung Hyung Don, he was sorry.

Why the comments resonated online

The renewed discussion quickly drew attention on social media, with many viewers revisiting Infinite Challenge as more than a cultural landmark—seeing it instead as an environment shaped by networks, hierarchies, and interpersonal dynamics behind the camera. The comments also renewed broader debate about how long-running variety productions handle injuries, medical follow-up, and the informal power structures that can form between senior and newer cast members.

Jung Hyung Don also signaled that his later intentions were not limited to exposing others. He said that seeing the older cast members again made him emotional, and that he may not have communicated everything carefully in his initial remarks—particularly because his focus shifted toward “exposing things.” He then sent a separate video message to the production team to clarify.

What happens next for Infinite Challenge’s legacy

Although Infinite Challenge is long past its peak era, controversies tied to its production culture continue to surface, especially as fans watch archival footage and search for explanations behind moments that once felt purely comedic. With Park Myung Soo acknowledging competitiveness and offering an apology, the dispute now centers less on whether discomfort existed and more on how senior voices shaped decisions such as medical treatment and who was prioritized in an emergency.

For viewers, the next step will likely involve how the production team responds to Jung Hyung Don’s clarifications and whether additional details emerge about the decision-making around the injury incident. For both comedians, the exchange may also influence how younger audiences interpret a show that is often remembered for its spontaneity—highlighting that even “beloved” entertainment can involve difficult, workplace realities.
