Why did Sunny threaten to throw YoonA down the stairs?

On the February 5th episode of JTBC 'Girls' Generation and Dangerous Teens', a mock trial was held to settle the fight between Kim Hee Hoon & Park Kyung Kyu.

Girls' Generation member YoonA admitted that, because of her overly playful personality, her fellow members have gotten annoyed with her on several occasions.

She shared that once, all the exhausted girls were sleeping backstage at a music program, but YoonA decided she wanted to pester Sunny with her aegyo.

In her tired state, Sunny responded to Yoona by threatening, "I'm going to push you down the stairs!"

Sunny was a bit taken aback and tried to throw Yuri under the bus with her saying Yuri was furious too, but Yuri remarked, "I don't remember,"leaving Sunny in a hilariously embarrassing and defenseless situation.
