+So there's this fella with a parrot. And this parrot swears
+like a sailor, I mean he's a pistol. He can swear for five minutes
+straight without repeating himself. Trouble is, the guy who owns
+him is a quiet, conservative type, and this bird's foul mouth is
+driving him crazy.
+
+One day, it gets to be too much, so the guy grabs the bird by the
+throat, shakes him really hard, and yells, "QUIT IT!" But this just
+makes the bird mad and he swears more than ever.
+
+Then the guy gets mad and says, "OK, fork you." and locks the bird
+in a kitchen cabinet.
+
+This really aggravates the bird and he claws and scratches,
+and when the guy finally lets him out, the bird cuts loose with a
+stream of invective that would make a veteran sailor blush.
+
+At that point, the guy is so mad that he throws the bird into the
+freezer.
+
+For the first few seconds there is a terrible din. The bird kicks
+and claws and thrashes. Then it suddenly gets _very_ quiet.
+
+At first the guy just waits, but then he starts to think that the
+bird may be hurt. After a couple of minutes of silence, he's so
+worried that he opens up the freezer door.
+
+The bird calmly climbs onto the man's out-stretched arm and says,
+"Awfully sorry about the trouble I gave you. I'll do my best to
+improve my vocabulary from now on."
+
+The man is astounded. He can't understand the transformation that
+has come over the parrot.

+SPAM may be famous now, but it wasn't always that way. Fact is, SPAM hails from some rather humble beginnings.
+
+Flash back to Austin, Minnesota, in 1937.
+
+You're right. There isn't much here, except for an ambitious company called Hormel.
+
+These good folks are about to hit upon an amazing little recipe: a spicy ham packaged in a handy dandy 12-ounce can.
+
+J. C. Hormel, then president, adds the crowning ingredient: He holds a contest to give the product a name as distinctive as its taste.
+
+SPAM soars. In fact, in that very first year of production, it grabs 18 percent of the market.
+
+Over 65 years years later, more than 6 billion cans of SPAM have been sold.

+Tyger! Tyger! burning bright
+In the forests of the night,
+What immortal hand or eye
+Could frame thy fearful symmetry?
+
+In what distant deeps or skies
+Burnt the fire of thine eyes?
+On what wings dare he aspire?
+What the hand dare seize the fire?
+
+And what shoulder, & what art,
+Could twist the sinews of thy heart?
+And when thy heart began to beat,
+What dread hand? & what dread feet?
+
+What the hammer? what the chain?
+In what furnace was thy brain?
+What the anvil? what dread grasp
+Dare its deadly terrors clasp?
+
+When the stars threw down their spears
+And water'd heaven with their tears,
+Did he smile his work to see?
+Did he who made the Lamb make thee?
+
+Tyger! Tyger! burning bright
+In the forests of the night,
+What immortal hand or eye
+Dare frame thy fearful symmetry?
