Ford was holding a small glass jar which quite clrealy had a small yellow fish wriggling around in it.
Arthur, the Galaxy's a fun place. you'll need to have this fish in your ear.
"The Babel fish", is a small, yellow leech-like fish, it is probably the oddest thing in the Universe. It feeds on brainwave energy received not from its own carrier but from those around it. it absorbs all unconcious mental frequencis with nerve signals picked up from the speech centres of the brain which has supplied them. The practical upshot of all this is that if you sitck a Babel fish in your ear you can instantly understand anything said to you in any form of language.
Arthur fell on the ground because he couldn't see anything cause of the yellow fish in his head, but he could understand the vogon leader now.
I can't see anything!
