Bit Rate versus Sample Rate

I've been asked to explain bit rate versus sample rate to a
non-technical audience. Can anyone think of a good *analogy* to help
explain the difference?
Sample rate is an indication of bandwidth (it is twice the bandwidth).
Word length is an indication of dynamic range (each bit doubles the range).
For uncompressed data, bit rate is the sample rate times the word rate
times the number of channels.
Once you start talking about compressed audio, all bets are off.
But literally, bit rate is how much data you can fit through the hose.
