Seinfeld: Before Kramer's first name was made known

As far as I remember, until the “Cosmo” episode Kramer had never introduced himself using anything beyond his surname… not an initial, not an honorific; except for (and only if this was before that episode – i forget) H.E. Pennypacker and/or {mumblemumble} Nordstrom as pseudonyms.

Morty Seinfeld would always address him as “Mr. Kramer.” This started in the first season when a different actor was playing Jerry’s dad.
