This week (the week after Easter) is National Egg Salad Week. Essentially it’s a way to get rid of those leftover hard-boiled eggs that the Easter Bunny left behind.

The University of Illinois Extension offers some Facts for Families for National Egg Salad week, including this:

Hard-cooked eggs should be stored in the refrigerator and used within one week, advises Carol Schlitt, University of Illinois Extension nutrition and wellness educator.

When storing hard-cooked eggs, you may notice a “gassy” odor in your refrigerator. The odor is caused by hydrogen sulfide that forms when the eggs are cooked. This gas is harmless and usually dissipates within a few hours.

Hey, remember the “Nerds” series of sketches on Saturday Night Live, and how Lisa Loopner’s mother, played by Jane Curtin, always offered people her “famous egg salad”? Gilda Radner played Lisa Loopner, and Bill Murray played Lisa’s boyfriend, Todd.

Below, Mrs. Loopner offers Lisa some advice as Lisa prepares to go to her prom. Go to 1:45 in the video for the egg salad part (full transcript here).

Now, listen, what I’m about to say is very hard for me to say. Lisa, dear… making a baby is like… it’s um… it’s like making egg salad. You, the woman, produce the eggs, and the man furnishes the mayonnaise—of course, you don’t need chopped celery for… Oh, I’ve just given you my egg salad recipe, and I was saving that for your 21st birthday!

Even if your egg salad recipe isn’t as famous as Mrs. Loopner’s, have a great National Egg Salad Week.
