In this week's episode, Yoon Hoo had to choose one friend to bring along on their latest trip. He abstained from choosing any of his friends and chose Jia instead. "I have too many best friends at school, so if I bring just one, it would be unfair," he reasoned.

"There are 32 people in my class, and I have 17 best friends," he said.

Wow - that's more friends than a lot of people have! How many best friends have you got?
