Short Words to Explain Relativity

There's nothing wrong with long words. I use them all the time. In fact I got rumbled as the sender of a joke valentine's card because I used the word 'fundamentally' and (as the recipient of the card said) "you're the only person in the office who knows how to spell it". What an inaccurate and depressing statement.

Anyway, what that rant brings me to is an attempt to explain the theory of relativity in words of four letters or less.

Although funny and oddly informative, it brings me to the inescapable conclusion that, sometimes, less is less.
