zero calorie dip wtf?

[turnipmonster]

last night when I was in the grocery store I noticed this stuff. wtf? obviously it cannot be zero calories, so I read the label thinking it was some rounding thing, like it would contain 1k servings of 0 calories apiece and actually 1 serving would have .002 cals or something, but it was only 2.5 servings. wtf?
