The H Is Silent

Linda was reading riddles from a book and the kids and I were trying to guess the answers. She read through a couple which referenced elephants and I passively answered "elephino" to one of them, simply making reference to that popular riddle. Nobody seemed to catch on, so after Linda had read a few more I told the kids I was surprised they hadn't heard this one and asked them, "What do you get if you cross an elephant and a rhino?" They made a few wrong guesses until finally Mia, who must have heard me earlier but hadn't really processed what she heard, said, "helephino?"
