Beer is essential at any tailgate party, but a granny chugging a beer bong isn't what you typically expect to see at this pre-game ritual.

At a recent Penn State/Purdue tailgate party a group of 'college kids' load up a beer bong (funnel) then hand it over to an old woman as the crowd cheers her on. In the spirit of all college keggers, the granny downs the brew like a seasoned veteran.

I know what you're thinking, you wanna party with this gal. Of course, who wouldn't want to slam a few cold ones with their grandma.

Watch as granny shows these college kids how it's done.
