“If a time traveller wanted to go back in time to a specific date, we could probably draw up a little phrasebook of the modern words that are likely to have sounded similar back then,” he told The Times. “You wouldn’t be able to discuss anything very complicated, but it might be enough to get you out of a tight spot.”

When I travel back in time, I'm bringing one of these. It'll get me out of a tight spot if the phrasebook doesn't work.

You should know that when you travel back in time you cannot wear clothes. Unless, of course, if you are a metal framed machine, then its OK.

Didnt you read the manual? Silly time traveler.
