Why bother with having a tree in your backyard that grows just oranges, or just lemons, when you can have one tree that simultaneously grows peaches, apricots, plums, and nectarines or oranges, mandarins, lemons, limes, tangellos, grapefruit, and pomellos? What you need is a Fruit Salad Tree from the Fruit Salad Tree Company. My wife insists these have to be a joke, arguing that everyone would already have a fruit salad tree if they were really possible to buy. I, on the other hand, think they're real... maybe because I don't know much about botany. But I figure they're just grafting different types of trees together. (via About.com's urban legends forum)
