AOA--like so many before them--attempted to dance to a twice sped up version of their new song "Good Luck" on the May 18 episode of 'Weekly Idol.'
The girls were doing swell, dare I say even spectacularly; that is until ChoA's brain suddenly farted and she totally forgot what she was doing...and where she was. She barely managed to catch on at the end, right before the song ended.
It's actually kind of cute how flustered ChoA became trying to keep up. Watch for yourself in the clip above!
