Someone needs to invent a mechanism to ensure the proper dip to dipping item ratio. It's never even, and it just leads to a vicious circle. I'm out of pretzels but not hummus, I'll get a few more pretzels. Crap, now I have pretzels left and I'm out of hummus. I'll get a dollop more. And so on. Until the family size hummus is gone. I'm pretty sure this is how the arms race started, except with uranium instead of hummus.
