You know how on “Inside The Actors Studio” they ask people what the best sound is? I have heard it answer, by more than one actress as “a baby’s laugh.” Totally pretentious, but also totally correct. Jacks laugh is the BEST! It rocks his whole body, even his little tongue trembles with delight. Now I will have to revise my answer if I ever run in to James Lipton and he starts questioning me.
