New twist on the "best beer" question

Say you want to give a brief beer tutorial to somebody
who is interested in beer but only knows whatever style
is most popular in your country/region (e.g., for the USA,
light lager).  Assuming you have access to any beers you
like, and picking a semi-arbitrary number, what five beers
would you use to help demonstrate the range of styles and
flavors beer can have?
   I have my own idea, but would be interested in seeing
what others have to say.
