What if Freud had been a woman?
Sex would not be considered the primary force that drives human behavior. Instead, it would be Fear of Having a Large Behind. All men would be haunted by a condition known as "penis shame." The mind would not be divided into the Id, the Ego and the Superego but the Shoe-Desire Region, the Weeping Center, and the If-You-Don't-Know-What-You-Did-Wrong-I'm-Not-Going-to-Tell-You Lobe. Also, sometimes a dried apricot is just a dried apricot.
What if wishes were horses?
Then beggars would ride. But so would everyone else. We would each have, like, 7,000 horses. They would completely paralyze civilization, consuming all vegetable matter in a week or less. Continents would rise several feet, just from accumulated poo. And anytime anyone wished for no more horses, another horse would appear. The world would end in a terrifying, thundering apocalypse of horses, is what would happen.
What if, as originally predicted, heavier-than-air flight had actually been impossible?
Rocket-propelled blimps. Travel would take a little longer, but the 9/11 plot would have failed, comically.
