We have put up our own Halloween logo and it looks like this for this year.
Which reminds me of Google and Yahoo's past logos for this day. Check Halloween 2004 and Halloween 2005, which also sports Jeeves.
Let's also not forget Cre8asites Halloween logo.
But did Google stop with the AdSense themes, remember the AdSense Halloween theme?
