Plum Perpetuation

            When the space aliens came, they were especially interested in plums. “So you’re telling me,” one said to me as he wiped purple juice off his mouth area and held up a pit, “that this has everything it needs to create a tree that will create hundreds more of these?”
            “Yes,” I replied.
            “It’s astounding and unbelievable! With such an exponential plum growth rate, the whole planet should be plum trees!”
            For hours I tried to explain reproduction.
            Though they still didn’t understand the concept of plum perpetuation when they left, planet earth now has a lively interstellar plum trade.
