When the international super star Psy was making arrangements for his latest video shoot, he said it "is going to be fun." He apparently was not joking.

Earlier in the week it was announced that famous entertainers Yoo Jae Suk and Noh Hong-chul would be appearing in Psy's new music video along with fellow comedian HaHa and Brown Eyed Girls singer Ga In. Now the list of celebrity appearances has gotten much longer.

Psy has confirmed that all of the members of the hit TV variety show Infinite Challenge will be included in the "Gentleman" music video scheduled to start filming April 7. The previously announced celebrities appear alongside Park Myung-soo, Jung Jun-ha, Jung Hyung-don, and Gil in the Saturday evening MBC television program Infinite Challenge and now they will all be together in a new form - appearing in what is sure to be the best music video of the year.

The ridiculously popular Infinite Challenge is heralded as the first ever "Real-Variety" show in Korea. The vast majority of it is unscripted, meaning the cast members have to be clever and hilarious in their own right and have a good working relationship with each other. The format is similar to that of challenge-based reality shows in the West, but as the challenges are usually ridiculous or impossible, it ends up turning into more of a satirical comedy than anything else.

Infinite Challenge has the largest market share for its time slot and is cast members are known throughout South Korea as some of the funniest, most entertaining men in the country. Add them in with the quirky Psy and you have a winning combination we can only assume will mean "Gentleman" is going to have a darn good music video.
