U.S. factory farms are raising more animals than ever before. Together, the 1.7 billion confined animals produce an appalling 941 billion pounds of manure each year — double the weight in human sewage produced by the entire U.S. population.
But I bet their poop is great for growing the grasses they eat. It’s probably also really good for tourists, who it seems to attract and that they also eat.
That’s ridiculous and was clearly shown to be false by my joke.
Obviously, hippos evolved so their poop was irresistible to tourists. This is something my joke mentions to explain why hippos are always attacking tourists.
