The annual Montana State Society Rocky Mountain Oyster Festival, better known as the Testicle Festival, has a regal new theme this year.

The event’s 2013 moniker: “A Royal Ball.”

Now in its 9th year, the Testicle Festival will again be held at the Arlington American Legion Post in Virginia Square (3445 N. Washington Blvd), from 6:00 to 10:00 p.m. on Saturday, May 18. Tickets are $25 online or $30 at the door. Attendees must be at least 21 year of age.

The price of admission will buy you “all the Rocky Mountain Oysters, beer and Crown Royal you can handle,” organizers say. Entertainment will be provided by the Will Gravatt Band, while the testicles will be fried by Frank McGraw, who’s billed as “Montana’s most famous ball chef.”

“Coming to us straight from the original Rocky Mountain Testy Fest at Rock Creek Lodge outside of Missoula, Frank’s tasty recipe has an authentic zest that helped set a record last year for most pounds consumed,” according to the Montana State Society website.

Last year festival-goers in Arlington consumed 110 pounds of bull and bison testicles, 84 liters of Crown Royal and 1,500 cans of beer. The 2012 theme was “Legends of the Ball.”
