What's your favorite Google search trick?

Here are just a few:

• I love that you can type "track xxxx" with xxxx a UPS / fedex / DHL / USPS tracking number, and get the info right away. And the dictionary definitions are great, plus it does math! Awesome. I love teh Google.
•  Go to local.google.com and doing something like: pizza near 123 Some Street, MyCity
•  Typing a movie title with your city or zipcode gets you showetimes, and reviews.
•  I use it as a dictionary all the time.   google search define:word
• If I were teaching a class, I wouldn't overlook the simple, magical quotation marks. You'd be surprised how many people don't know about them.
•  The ? wildcard is quite impressive. For example: 1 cup =? ounces
• Google two cities, get airfare links.
• Find lyrics to a song:   "Bittersweet Symphony" lyrics
• link:[url of a website you are interested in] tells you what other sites are linking to it.
• Googlism - what google knows about you.
• googlefight - fight between two google searches - Death and taxes! God and Satan! Newsfilter and Funfilter
• blag (purple|monkey|dishwasher) is the equivalent of searching for: blag and one of either purple, monkey or dishwasher
