The movie poster of "Sans Respirer" on the back of Morgan's office door when he is talking to Hannah lists the names of Matthew Miller and Scott Rosenbaum, two of the show's writers.
The comic book that Chuck is reading while waiting for Manoosh is called "Y: The Last Man, Volume 5, The Ring of Truth".
The bar that Chuck hangs out in with Manoosh is named "Two and A Half Amigos!" This is a play on The Three Amigos which guest star Chevy Chase was featured in. It's also a play on the title of the series Two and a Half Men.
