The cast of MBC's 'Infinity Challenge' has been selected to be the new CF models for soft-drink maker Coca-Cola.

The cast members - Yoo Jae Suk, Jung Hyung Don, Noh Hong Chul, HaHa, and Park Myung Soo - were selected thanks to their vibrant, cheerful personalities. "They are known as today's best entertainers to the young generation thanks to their cheerful energy and fun-loving antics," said a representative for Coca-Cola. "It was decided that their positive traits would accentuate Coca-Cola's own cheerful and fresh character."

The 'Infinity Challenge' cast will act out popular school-age tropes in the new commercials, the first of which is scheduled to hit the airwaves on April 12.
