A woman goes into an art gallery and sees two still-life pictures. Both are of a table laid for lunch with a glass of wine, a basket of bread rolls and a plate of sliced ham. However, one picture is selling for $75 and the other for $100. Curious, she goes to the gallery owner and asks him what the difference is between the two pictures. The owner points at the $100 painting and says, “You get more ham with that one.”
