This is a palindrome, that is, it reads the same forwards and backwards. If you reverse the order of the letters in this phrase and play around a bit with the spacing, you get the same thing. Isn't that cool?

Other palindromes are "race car", "Madam, I'm Adam", and "Do geese see God". A lot of palindromes somehow seem to have a weird meaning, particularly if you've been blazing the ganja. If you like palindromes there are lots more at both at the palindrome node and this URL:

Try and think up some palidromes on your own. Its hard, and I guarantee you won't come up with anything that makes close to as much sense as "a man, a plan, a canal, panama", which even manages to be a historical reference. But it's a mildly amusing way to kill some time at work.
