This one came to me in an SMS yesterday:

Google has completed 12 this year..
We just have 1 more year left to use it before it becomes.....

a teenager and stops answering questions.

I forwarded it to a couple of friends before realizing that it was Google's 13th birthday yesterday (did you see their Doodle?).

Oops, so Google is a Teenager already. - though a well-behaved one, considering that it is still answering all my questions :-)
