Jack hosts the 200th edition of Haveil Havalim. He wanted it to be celebratory, but that was not to be. His post has nothing to do with the movie. I just happened to like the movie, and I thought it would make a good pic for the 200th edition.
From Wikipedia, about the movie Harvey: The story is about a man whose best friend is a “pooka” named Harvey—in the form of a six-foot, three-and-one-half-inch tall rabbit.
