Thought of this while smelling some money:

It is impossible to describe a smell without relating it to another smell. If you were talking to a person with no nose how would you describe the smell of a freshly cut orange, or the toilet after school camp serves shellfish.

Same goes for sound really, except deaf people can often still 'feel' alot of sounds.
Sverre, actually we taste in our noses much more than we do with our tongues. Your tongue really only tells you Bitter/Sweet/Sour/Salty, while your nose says Oranges/Mashed Potato/Red Wine. This is why Wine Tasters place so much importance on smelling the wine before they taste it.

You can notice this if you try eating while holding your nose, or when you have a cold. Food tastes different, because you only get part of the flavour.
