The X-Files, Season 4

The Cigarette-Smoking Man:
Life... is like a box of chocolates. A cheap, thoughtless, perfunctory gift that nobody ever asks for. Unreturnable, because all you get back is another box of chocolates. So, you're stuck with this undefinable whipped-mint crap that you mindlessly wolf down when there's nothing else left to eat. Sure, once in a while, there's a peanut butter cup, or an English toffee. But they're gone too fast, the taste is fleeting. So you end up with nothing but broken bits, filled with hardened jelly and teeth-shattering nuts, and if you're desperate enough to eat those, all you've got left is a... is an empty box... filled with useless, brown paper wrappers.
