Alcohol

Here's what the Encyclopedia Galactic has to say about alcohol. It says that alcohol is a colorless volatile liquid formed by the fermentation of sugars and also notes its intoxicating effect on certain carbon-based life forms.

The Hitchhiker's Guide to the Galaxy also mentions alcohol. It says that the best drink in existance is the Pan Galactic Gargle Blaster.

It says that the effect of drinking a Pan Galactic Gargle Blaster is like having your brains smashed out by a slice of lemon wrapped round a large gold brick.

The Guide also tells you on which planets the best Pan Galactic Gargle Blasters are mixed, how much you can expect to pay for one and what voluntary organizations exist to help you rehabilitate afterward. The Guide even tells you how you can mix one yourself.

The Hitchhiker's Guide to the Galaxy sells rather better than the Encyclopedia Galactica.
