And another (tune sorta like itsy-bitsy spider):

Shizuka no kohan no mori no kage kara -
Otoko to Onna no koe ga suru...

Aha! Iya! ...Chotto dake yo!!

(Translation):
In the shadows of the forest by the quiet pond -
come the voices of a boy and a girl...

Ahhh! No (Stop it)! ...Is that all?!

And my favorite Japanese poem:

He nari totte
ada to omou na
morobi to you.
BUU~ to nari totte
Hotoke nari keri.

When you fart,
don't be ashamed of yourself.
For when you *POOT*
you become like Buddha.

 

Just remembered another:

(Melody of Bibbity-boppity-boo, or whatever that Disney song is):

Yamete yoshite,
sawaranaide,
aka ga tsuku kara.

Anta nanka kirai yo,
kao mo mitaku nai.

Trans:
Stop it!
Don't touch me,
You are dirty [as in shedding dead skin flakes].

I hate everything about you
and I don't want to see your face.

I'm just doing my best to expose the best of Japanese culture.
