They're beautiful. They're talented. And in some cases, k-drama actors are also quite funny. And we're not just talking about their onscreen performances. Quite a few k-drama actors have a wicked sense of humor that endears them to fans and fellow cast members alike.

Park Shin Hye recently demonstrated her sense of humor when she held a fan meeting recently in New York City. When a fan asked her what it was like to work with so many "hot" actors on the set of "The Heirs," she asked the audience whether her working with Lee Min Ho and Kim Woo Bin made them jealous? She joked that so many of her friends were so envious. The intensity of their jealousy made her afraid to fall asleep at night. She's so sweet that her wry sense of humor caught the audience off guard and mader her seem even more charming.

Lee Jong Suk has famous for being funny on set even if it's hard to imagine him goofing around on the set of his new serious drama "Doctor Stranger." His "I Hear Your Voice" co-stars commented on his on-set antics and funny mannerisms, which he played up for laughs. Lee Bo Young said that he often made her laugh on set. Kim Woo Bin said that he and Lee Jong Suk laughed so much together on the set of "School 2013" that it was "almost impossible to act."

So Ji Sub was surprised to discover he could do comedy when he starred in "The Master's Sun" and he credited a lot of his performance to his co-star Gong Hyo Jin, who is known as "The Queen of Comedy." She was surprised when she met him. She expected the actor to be reserved in person but found that he was very funny on set.

"When I first met him, I thought he was really quiet and shy," she said. "But he laughed more than I expected. He likes to joke around when he talks to you."

And when an interviewer asked So Ji Sub why Gong Hyo Jin was laughing, he said, "She's always like this."

She laughs a lot both in and out of character.

Gong Hyo Jin also said that she also shared plenty of laughs with Cha Seung Won, her co-star in "The Greatest Love."

Kim Kang Woo is said to be cracking up his co-stars with his antics on the set of "Golden Cross." The actor, who plays Kang Dong Won in the drama, is known for making jokes and cheering up everyone on set.
