5 Eggs by Thomas M. Disch (Orbit #1, 1966) begins with a man finding his bride to be has gone, after which he decides to go ahead with the post-wedding party anyway. As the story unfolds we find that she was a bird-like creature of alien origin, and that she has left him 5 eggs to incubate.
At the party we see the narrator greet and talk to a couple of guests and then, towards the end of the event, he can’t find the eggs. Eventually (spoiler) he finds cracked, empty eggshells in the kitchen, and finds a recipe card for Caesar salad (needing a similar amount of eggs). He then realises that the note was left for the cook by his avian fiancée and, at this point, he remembers her hilarity at cannibalism scene in Titus Andronicus.
For the most part this is a quirky but enjoyable enough story, but it morphs into a weak and contrived black joke at the end (and not one that is saved by referencing Shakespeare).
