This 100-year-old grandmother still knows how to party.

The Huffington Post reported that Marie Pope celebrated her 100th birthday with a game of beer pong and a sash declaring her age with family in a Chicago suburb.

A July 30 video posted to Facebook by grandson Trevor Pope shows Grandma still knows how to have fun.

“It was an excellent time, a really wonderful occasion,” Marie Pope told The Huffington Post.

Although she did take a birthday shot, Pope said she didn't drink much alcohol.

The clip shows the birthday woman making the game-winning shot -- and the roaring cheers of her family. What's even better? Pope said it was not her first time playing the game.
