fruit of their loins

My drink leaked on the fruit in my bag today. I had a red apple and the banana in there. I rinsed them off and stuck them in this basket to dry. When I came in after vehicle check out (at work) an additional piece of fruit had magically appeared. Did my apple and banana get busy while we were out of the room? Will their green apple offspring taste like a banana? These are my questions. Also, while I respect their compromise on color, wouldn't an orange have been more appropriate offspring?
