Hey, does anyone know if, in ANY episode, Newman uses his own name? I can easily think of episodes in which each of the main characters spoke their own names in the course of their dialogue. (Although a comprehensive list of this would be interesting to see)
The most obvious of which was 'The Jimmy' since this caused some of the characters to speak of themselves in the third person. ('George is gettin' upset', 'Elaine bought a new dress')
For Kramer: 'I'm Cosmo...Cosmo Kramer' in 'The Switch' Jerry: '...then I want to be called Jerry the Great' in 'The Maestro (I'm sure there are countless others)
I don't think Putty used his name at all either. I'm only thinking of regulars on the show obviously.
