We just had dinner at our favourite tempura restaurant and these are some of the jokes our elderly Japanese friends told us:
When a Japanese tells you “Agetofu” (literally: fried tofu); he or she is trying to say: “I get off” in English.
When he or she says “Saito Shingu” (literally: Saito family’s worship items); he or she is trying to mean: “sightseeing” in English.
When he or she says “Hota imo ijiru na” (literally: Don’t tamper with the picked potatoes), he or she is trying to mean: “What time is dinner?” in English.
Here's another common joke: Whenever I go, "I will show you...", kids would exclaim "shoyu!", thinking that I am talking about soy sauce.
And this is what I tell my kids when I teach them days of the week.
Monday: Manjyu (Japanese bun) Day.
Tuesday: is Tuesday. I couldn’t think of anything funny.
Wednesday: Ue (up there) nesu Day.
Thursday: Tasukete (Help!) Day.
Friday: Ebifry (fried prawns) Day.
Saturday: Satsuma imo (sweet potato) Day.
Sunday: ichi, ni, san (1, 2, 3) Day.
Just for laughs!
