References in popular culture
I'm moving these here, because it seems to me that they are not important in the works in which they occurjust passing references. This is underlined by the fact that they are not referenced. And they do not illustrate anything important about any cultural role of egg sandwiches.  (talk) 

In the Red Dwarf episode "Thanks for the Memory", Arnold Rimmer is given a party celebrating his death day.  Once back on the ship, Dave Lister wishes he could have a '...triple fried egg butty with chili sauce and chutney.'  Soon after, Rimmer in his drunken state wishes for the same thing.  Holly produces one for Rimmer and after taking a bite he exclaims 'I feel like I'm having a baby!' The scene continues on for several minutes.

In the Biz Markiesong "Dinner Date," Markie expresses his desire to eat an egg sandwich off of a woman's rear end.
