Man #1: I hear Starbucks is introducing its new 31-ounce drink size today.

Man #2: Disgusting, who would want that?

Man #1: Apparently they are introducing it in places like Florida, Georgia, Alabama, Mississippi, Louisiana, Kentucky, Texas, and South Carolina.

Man #2: Ah yeah, the fat belt. Makes sense.
