The members of 'Infinite Challenge,' the MBC variety show going on its 9th year widely regarded as the living legend of entertainment shows, will attempt to teach about 30 idol members on the topic of Korean history.

On the episode to be aired on May 11, each member will provide a Korean history lesson in the 'TV Lecture Special.'

The show will feature the members' stressful lecture preparations and their struggles to brainstorm creative ideas to present what can often be dry and factual. Usually thought of as below average in terms of book smarts, the members of 'Infinite Challenge' went as far as to take lessons themselves in order to provide a fun educational opportunity.

In front of a crowd of idol members, the members were reportedly caught off-guard, showing signs of nervousness in the presence of many who are in fact still in high school.

According to sources, most participants were able to keep up their interest level despite the extended hours of shooting that spilled into the late night.

The 'TV Lecture Special' episode of 'Infinite Challenge' will air on May 11.
