First part of the joke:
The dalai lama walks into a pizza shop and says "Can you make me one with everything?" Second Part:
The proprietor of the pizza shop says "that will be 15 dollars", the dalai llama hands the proprietor a 20$ bill.. the proprietor stuffs the bill into his pocket.. the dalai lama says "Don't I get change?"... the proprietor says "Change must come from within".
