My top two favorite places I've found my own stolen cake pics:

... Not counting the Russian adults-only site I was too afraid to click on ...

The place that categorized my alien cake into "funny cakes" but then credited me as "Underground Kings"

(which sounds like a drug gang instead of a bakery)

The newest one, which has a christening cake as a downloadable something or other ???, and titled it _Abbie Labels Cake Topper Lego Polka Dot Scrabble Wedding Pic_

So I had made a boobs cake for a bachelor's party, and I found it on some website when I was googling "Di's Sweet Treats". Don't really remember the site, but next to  my cake was porn advertisements. I was not super surprised, but was pretty grossed out.
