A Visit to the Lion
Rav Moshe Aharon once said he would like to see a real lion. His son Rav David drove him to the zoo, and when the tzaddik saw a lion for the first time in his life, he said, "How great are Your works, Hashem."
He then looked at the lion and greeted it, "Greetings to you, your majesty, king of the animals." He stayed there for a long time, watching the animal.
