Rey's school taught him this...

Rey learnt this in school, a song about 'farting!'. Quite a cute song and the tune has been on my mind the whole night. Sang in Japanese "Bokura wa PUuu, bokura wa puuu, Bokura wa Pu PU PU!" (simply translated to as "we are farting X 3"). That easy. So you can sing a Japanese song!

ps: the new drama (romantic princess) that i thought was boring is getting more and more interesting!
