Tom and Joe bought two identical and adjacent plots of land. Tom is a well known mobster. Joe is just your regularâŚwellâŚJoe. Anyway, Joe starts building a house on the plot. Tom is right behind him. Every time Joe builds something, Tom does the same. After a few months construction is done and the two houses stand side by side, identical in every way - from plumbing to shingles. A couple of years pass and Joe decides to sell the house. He puts up a âFor Saleâ sign with a price of 2 million dollars. Tom sees it and quickly also puts up a âFor Saleâ sign, only for 3 million dollars. Joe, confused, politely asks his mobster neighbor: â Hey Tom, our houses are identical. youâve copied every little detail from me. And now weâre selling and you are asking 50% more than me. How come?â Tom smiles and says, âyeah the houses are the same, but I donât have a mobster for a neighborâŚâ
