In a bit by Lewis black he overheard one girl say this to another. He went on to say that this is the type of nonsensical utterance that if you think about it too long you will develop an aneurysm and your head will explode. In fact, in many places trading a horse for a year of college is acceptable. Horses can be sold for $10s of thousands of dollars.
I was broke so if it wasn't for my horse, i wouldn't have spent that year in college.
