Welcome to Dealighted.
As for the inquiry, not happening. For example, just look each company's market cap to determine the validity of such a rumor. Microsoft is currently at $169.4B, versus Google is currently at $86.03B.
On a related note, Microsoft reportedly could be once again seeking to acquire Yahoo! search operations. I tend to doubt that report, but I could perhaps foresee some type of joint venture deal on the table.
