Girls Generation member Sunny showed off her witty quick thinking on stage.

Yesterday, an online community board revealed a video of Sunny with the title, 'Quick Thinking Sunny."

The video revealed a performance from their "Music Bank" last stage for their song "I Got a Boy."

In the video, Sunny's pink belt fell off her waist during the performance. Sunny, like a pro, did not panic and instead naturally pushed it off the stage. Her wit and quick thinking helped her and the group to finish of the performance smoothly.

This is not the first time Sunny has shown her quick thinking skills. 

Internet users commented, "Sunny is the 'quick thinking' queen" and "This is what you call a pro."
