I tried to translate this joke as best as I could, but I may have failed.

The original joke is that at first glance, ザーサイ (which means 'Chinese Pickles') looks kind of similar to the word ザーメン (which means semen).

I was trying to think of other food items that look similar to semen (or cum, jizz, etc.) and this was the best I could come up with.

I like this 'married couple' thing. It's cute.

In any case half of these are about to get deleted.

"Some semen sounds really good"

Given the fact of some of the Haruhi Suzumiya are mostly hentai...

ザーサイ doesn't look similar to semen.

The name "ザーサイ"(szechuan pickles) looks similar to "ザーメン"(semen).
