This does look like a funny little test, how silly can a rumor become before Yahoo longs stop believing. Next week is going to be fabulous, Boeing or The Biloxi Boy Scouts show interest according to sources.
people are jumping on the "google is going to BUY YHOO rumor" and that is totally false.
if you go back and read some of the articles, you will find GOOG is looking to FINANCE a buyout. they would finance the deal and presumably take a position in preferred shares (kinda like what YHOO did with Alibaba).
GOOG cannot buy YHOO and fold them into GOOG, the government would never allow it. they are already in the hot seat with other antitrust issues.
