Blogger... What Was It?

I thought of something I wanted to blog about today. Unfortunately I didn't write the thought down straight away... this was a very bad move! I remember thinking to myself, "Ooh, what a good idea..." and now it's reeeeeally bugging me what it was.
If I remember then I will of course come back pronto and blog it... but, you know, don't get too excited it was probably something totally random (as usual)!
