After Kramer has been kicked in his gourd by Crazy Joe Divola (his injuries would have been much worse had he not been wearing the helmet that he traded for with Newman), he is babbling randomly and blurts out "Yo Yo Ma". Jerry says, "Yo Yo ma?" and Kramer says, "What about him?"

Jerry then explains to George that Yo Yo Ma is a cellist and tells Kramer that he needs to see a doctor.
