When Lois is talking to the Red-Blue Blur on the phone, she asks "Can you read my mind?" This is most likely a reference to the song in Superman (1978) that asks the same question while Lois flies with Superman for the first time.
Lois is denied entry to a press society named after Edward R. Murrow. Mr. Murrow was an American broadcast journalist who came to prominence in the 1940s, especially WW2, and is considered a significant figure in setting standards for excellence in integrity and ethics in journalism.
The portmanteau 'Blur-etto' - used in the episode by members on the superhero appreciation website discussing the pairing of the Red-Blue Blur and Stiletto - is a joking reference to combined character names by fans as shorthand for specific relationships.
