Ok, one time then because the logo is on Google.nl (also some other homepages):

Search is "Sinterklaas Kapoentje",

google.nl/webhp?hl=nl#q=Sinter ...

Also

google.ro/search?q=Mo%C5%9F+Ni ...

google.hu/search?q=Mikul%C3%A1 ...

Only Google forgot to remove the logo today. It's not Sinterklaas anymore here in The Netherlands, only in Belgium.

Yeah, at
google.nl/webhp?hl=nl&outp ...

Ha, the logo changed since yesterday,

google.nl/logos/2010/stnicday1 ...

Google.be has "original":
