Passing the Buck

Someone once accused me of passing the buck.  I was rather surprised by this offer, because I had been expecting to have to pay a LOT more than a dollar to get rid of the company I had founded for making self-replicating blueberry smoothies (As it transpired, the process necessary for making self-replicating blueberry smoothies just so happened to open up a vortex to a parallel dimension inhabited by man-eating lemur-like critters, and thus my desire to get out of the self-replicating blueberry smoothie business).  So, I took out my wallet and handed him a buck.  He looked at the buck.  He looked at me.  And then he threw the buck back at me and stomped away.  Some people don't know how to haggle...
