Confused as I am?

Has anyone else noticed that on your dashboard and proflie pages on blogger the blogger symbol has a piece of cake with a candle in it? Ive paid close attention to this and am quite confused by this picture. I dont know about you but id like to know what we're supposedly celebrating? Aniversery? Holiday? I have no idea. I might write a letter to them asking that the cake be removed. I doubt ill get a response. Sad Face.  If you find any info on the unnessisary cake id be more then delighted to hear it. thanks. haha.
