h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I hate to disappoint everyone who have never experienced Cadbury's or Pemberton's, but...
Hershey's? CHOCOLATE?! Nah.
Obviously, the tour misses out the important stage where they add rancid margarine and ashes. How else would they achieve that distinctive aftertaste? Mmmm.

That's a pretty common reaction to the taste if you haven't been brought up on it like most Americans.

Hershey's executives insist that there is nothing rotten about the flavour.

But do consider that the original formula and taste was developed by a man who smoked several Cuban cigars every day...

and, presumably, spat in the ingredients afterwards.

He also invented beet-flavoured ice cream. But most folks agree that by then his taste buds were totally gone...
