Something about Yahoo! that 99% people don’t know

I came across something about Yahoo! that I can bet 99% of the people don’t even know.

Goto the Yahoo! Main page – www.yahoo.com
You see the logo of Yahoo! on top?
Turn on your speakers/headphone and then click the exclaimation mark i.e. “!”

Oh yea! you see! I can bet you never noticed this all ever before.
