J's dozen 

In pursuit of obtaining a larger quantity of the traditional dozen (12), in the same fashion that you would order a bakers dozen (13), the J's dozen (24) came about at bakeries and coffee shops in Colorado and NY.

"I'll take a J's dozen of those bagels." or "Just give me a J's dozen chocolate chip cookies."
