Turner and Hooch. Batman and Robin. Itchy and Scratchy. And now, Shake Shack and Dominique Ansel Bakery. History has seen its fair share of dream teams, but the upcoming collaboration between burger-and-custard experts Shake Shack and Cronut creator Dominique Ansel may be the most delicious.

Only on Tuesday, September 17th will Shake Shack shill a delightful creation dubbed "Cronut Hole Concrete". This super-limited edition treat will feature a serving of the Shack's butter caramel frozen custard with four cinnamon sugar "Cronut Holes", aka Munchkins on Lance Armstrong-level dope. They'll be available exclusively at the original Shake Shack location in Madison Square Park starting at 10a. But if you wanna hang with pastry star Dominique Ansel, you'll have to get there between 4p-5p, when he'll be handing out Concretes himself.

Be warned: it's a two-Concretes-per-guest limit, and there are only 1000 of these bad boys to spare. Though when the proceeds go to the Madison Square Conservancy and the New York City Patrolmen's Benevolent Association Widow and Children's Fund, you can feel a little less pathetic about lining up at 8a.
