A Zen Buddhist walks up to a hot dog vendor and says, “Make me one with everything.”

The hot dog vendor gives the Zen Buddhist the hot dog, and then the Zen Buddhist gives the hot dog vendor a five dollar bill. The hot dog vendor pockets the five and goes about his business.

After a few seconds, the Zen Buddhist speaks up: “Hey, what about my change?”

The hot dog vendor cooly replies, “Change comes from within.”
