“Hollandaise” sauce sounds like “Holland days.” Of course, there are jokes.

Wikipedia: Hollandaise sauce
Hollandaise sauce (/hɒlənˈdeɪz/ or /ˈhɒləndeɪz/; French: [ʔɔlɑ̃dɛz]), formerly also called Dutch sauce,[1] is an emulsion of egg yolk, melted butter, and lemon juice (or a white wine or vinegar reduction). It is usually seasoned with salt, and either white pepper or cayenne pepper.
 
Hollandaise is one of the five mother sauces in French cuisine. It is well known as a key ingredient of eggs Benedict, and is often served on vegetables such as steamed asparagus.

Did I ever tell you about the year I spent in Amsterdam, delivering eggs, butter, and lemons?
Of course, that was back in my Holland days…

Bedankt voor het luisteren!  I hope that means “thank you for listening”
Plus do JW’s English puns translate? Like this:
Every time I eat eggs benedict I’m reminded of my time in the Netherlands.  You know, my “Holland days.” 
However, that may not be funny in any language?
