A member at DigitalPoint Forums was told to learn how to spell negligible but searching for it in a search engine. So he entered in neglible (misspelled) into Google.co.uk (same works for .com) and Google did not offer up a spelling correction.
Instead Google shows the first result from www.misspelled.com/common/n.htm and then offers up those Middle of Page Google Refinements option, but for the word "dictionary."
Pretty cute.
