frog in my throat

A few weeks ago, I commented that I had a frog in my throat. Ro was astounded and perturbed. Once I explained it, he was less perturbed but still quite interested. Now, he revels in clearing his throat multiple times. The, in a raspy voice, he informs me that he has frog in his throat and requests a class of water. It's definitely a favorite phrase. He manages to use it almost every day. It takes many sips of water and much throat clearing to get the frog to go away.
