Today is Cinco de Mayo (the fifth of May), but Google does not have a logo on Google Mexico. (They never did)

and Yahoo has the very same logo they had last year.

Yahoo! is too poor to make their own logo!!
Plus, Google logos are the best!! more than Yahoo! and Ask.com

They doesn't care about Mexico because Google doesn't have office there, right?
