The Incredible Hulk in his secret identity was staying at a rooming house for a while, the same place that a blonde was staying at, and a character called "Professor Kroptokin". This looks like a reference to "My Friend Irma" because Irma stayed at the same rooming house as a "Professor Krepotkin". Marvel of course published the comic book MY FRIEND IRMA back when they were known as "Atlas", some years before they started publishing THE INCREDIBLE HULK.
Here are a couple of pages from issue #231 of THE INCREDIBLE HULK.
This "Kropotkin" resembles Orson Wells.
