ok, maybe not big... but funny!
Was just flicking through my new office calendar and stumbled across this great picture of a hipo's head appearing from beneath a whole lot of water plants - the quote underneath it reads:
"There's a fine line between genius and insanity. I have erased this line."
~ Oscar Levant. American pianist and actor.
I wish I could post the picture too - but the scanner here is one difficult beast to convince to do such tasks. You'll just have to use your imagination. :)
