Google and Sesame street

Since November 4th, Google has been changing its Logo with a character from Sesame street.
My question is.. what does google have to do with sesame street?? I mean even if it's Sesame Street's 40th anniversary..who cares?

Why should I be forced to see characters from Sesame street every single time I want to search for something?

Don't know bout you, but I actually found it kind of creepy/ extra weird..
The only time I can accept such a thing is if I was watching a Thanksgiving parade!
