Google has many uses, one of which being a spellchecker. But when a word has different spellings, whit different meanings, it is time to start experimenting with searching for the word in sentences.

This morning I was looking for the correct spelling of the plural of “son”. I was not sure if it was “sons” or “sones”. The first describes male offspring, the second apparently is: a unit measuring the loudness of sound as subjectively perceived, equal to a tone of 1 kilohertz at 40 decibels above the threshold where sounds become audible to the listener. Thank you Encarta. One of the pages in my search results was – What’s the plural of “Son of a Bitch”?!

I would answer #5, just because I find it hilarious. But I’m sure that many would choose the last answer
