LMAO av1. I do the same thing. Though, I'm singing all the time when I'm studying and stuff like that, too. >_< I think my parents get annoyed. Obaachan thinks it's funny.
jihye, I had the same problem in karaoke... With songs I didn't know very well, I sometimes was like, "lala soshite anata ni sasagemashou" or whatever. Depending on the song. ^^

You should have seen me singing enka. I went with my aunt and uncle and sang some serious enka with kanji I had no idea the reading for. So, it sounded like, "Kawa wa ummm no nagare no you ni..."

It was okay, though. Everyone started whispering the kanji to me. But as soon as I don't know one kanji, they assume I don't know any of them.
I kept insisting, "I know everyday kanji, but not the kanji for lovers' suicide!" but no one believed me.

I wonder why. Baka hakujin kamo ne.
