79-year-old grandma does keg stand at graduation party

One grandma celebrated her grandson's high school graduation in an ... interesting way.

79-year-old Muriel Holshevnikoff mentioned that she wanted to do a keg stand at the graduation party. Her granddaughter, Madison Munoz, didn't think she was serious -- until she was going for it.

Munoz captured the moment and shared it on Twitter:

"Everyone was egging her on and she was excited," Munoz told Inside Edition. While partygoers were shocked, they all thought it was funny.

"The whole party had a good laugh about it. She was definitely the star of graduation weekend," Munoz continued. "I had people messaging me saying, 'Your grandma is my idol.'"

Party attendees weren't the only people impressed; Munoz's tweet went viral with over 2,000 retweets and 12,000 likes.

Munoz, a 20-year-old Texas A&M University student, told Fox News her grandma's enjoying the internet fame.

"She thinks all of the attention is funny and is having a fun time with it," Munoz told Fox. "She got an Uber from the airport yesterday and told us that she told the driver that she's famous now!"
