While on an aid mission to Eastern Congo, UFC veteran Justin "The Viking" Wren got to meet and interact with the children of the Mbuti pygmy tribe who have never seen a white person, much less touched one.

According to Wren, it was also the first time they'd seen either arm hair or a thick Viking beard.

The gentle giant captured their smile-inducing reaction on his iPhone 4S, and even turned the camera around so they could see see themselves being recorded.

"We are working to help these people in need," Wren writes, "but that doesn't mean you can't have fun while doing it!"
