On December 10, Korea Grandma's YouTube Channel featured a video of Park and her friends attending a '19+' performance titled 'MisterShow', strictly geared towards women.

Park's granddaughter Yura commented, "All of my friends around my age recommended 'MisterShow' after watching it.  So I decided to go watch the performance myself with my grandma and her friends."

Once the group arrived on site, Yura said, "All cell phones off, right?"  Hearing this, grandma Park barked, "What's the big deal, telling us to shut off our phones and all?"

However, despite her previous response, the grandma's faces lit up once the show started.  Grandma Park gazed intently towards the stage as handsome muscular men in their 20s and 30s ran around, topless.

Grandma Park even got the chance to go on stage to experience the heated performance first hand.  She covered her face with embarrassment and froze on stage, causing much laughter.

Once the sexy dance was over, the MC asked, "So how was it?" to which Grandma Park answered, "I can't say in words."

After the show, the ladies went backstage to meet with the young men as they happily took photos together and received autographs.

Grandma Park raved about the jaw-dropping event, "I definitely have to come back again with my daughter."  She said to the performers, "You guys were abs-olutely fantastic! I feel ten years younger."

Towards the end, Grandma Park's friend Ok Hee added, "The show was great and everything but it felt like something was missing...You know like something...a bit more extra..." causing Yura to burst out into laughter.
