Rhi....No way!

Owen had a rhino on his onesie. He called it something else, so I told him it's a rhinoceros. He tried to say the word, but couldn't, so I told him it's a rhino. After a few rhi rhi rhi tries, he says to me, "Help!" I tell him "Rhi" "No". For some reason, he can't have "no" at the end of a word, so he says "rhi....norhi" whch then morphs into "rhi...no way."
