I finally got a picture of this........ it's one of the very first Japanese hiragana signs I could read!!!! (it's in the toilet of my high school's bathroom)
The 2nd line says:
and kudasai means please or please I'll have... so when ya put it together in my engrish brain it reads: please shit or.... ill have a shit please
Now a few months later I realize SHITe KUDASAI means to do something politely... but I still get a laugh every time I sit on this loo.
