Sunmi attempted to teach fellow Wonder Girls members the art of mastering the 'sexy' behind the dance moves to "24 Hours" on the latest broadcast of 'Weekly Idol.' 

As Sunmi showed the choreography, the rest of the Wonder Girls copied her dance moves the best they can...until Sunmi abruptly stopped to abashedly declare that she forgot the rest of the moves. MCs Jung Hyung Don and Defconn reassured her, "It's okay, it's okay, they remember!" Thankfully, Lim, Yubin, and Yenny were able to perfectly replicate the choreography, especially Yubin and Yenny! 

Watch for yourself how well Wonder Girls learned the moves to "24 Hours" in the video above!
