Nah, the weirdest sonic product is the Chicken Fried Steak Sandwich which is just some walmart brand steak deep fried and put on a bun.

However, they do have some of the best burgers in the business and they're infinitely more customizable than any other fast food place. Plus the ice rocks and the drinks can't be beat. The ice cream machine is always on too so you can get shakes even after 10:00 if they're still open.
