"After they had thrown a welcome party for their mango, which ended at 11 at night, they decided they should put it in some chemical fluid to preserve it forever. Through the rain they drove to the Agricultural Exhibition Center, but in vain - no such fluid was available there. They drove on (by then, it was already 3 a.m.) to the Museum of Natural History, where they arrived at dawn. So it took them two to three hours to drive a couple of miles, which either means that the streets were crowded with frantic mango preservers, or their revolutionary fervor had completely muddled their sense of direction. Their trip to the Natural History Museum proved to be lucky: the mango was carefully placed inside a glass jar filled with formaldehyde. In the morning of 6 August, they could take their mango back home."
