KT's started using Bob Ross to advertise its "Qook and Show" service:
The commercial, which mixes footage of 밥로스 아저씨 with some white guy they stuck in a wig, was made last month but has hit the internet, and the forums, recently. As is the norm for Korean TV shows, music videos, and commercials, this also has a "making" video where at the two-minute mark they talk a little with the foreigner they recruited.
Other commercials with celebrity impersonators include Faux-bama for Skylife and Faux-prah for IBK. If they use Mr. Rodgers next I swear to God I'll beat the whole cast and crew with their own Keds.
There are certified "Joy of Painting" contacts throughout the world, and South Korea's is in Cheongju.
