Life is like a box of chocolates.

"Life... is like a box of chocolates -
a cheap, thoughtless, perfunctory gift
that no one ever asks for,
it cannot be returned because
all you get back is another box of chocolates. 
So, you're stuck with mostly undefinable
whipped mint crap, mindlessly wolfed down
when there's nothing else to eat while
you're watching the game. 
Sure, once in a while you get a peanut butter cup
or an English toffee but it's gone too fast
and the taste is fleeting. 
In the end, you are left with nothing
but broken bits filled with hardened jelly
and teeth-shattering nuts,
which, if you are desperate enough to eat,
leaves nothing but an empty box of useless brown paper."
