For the last week or so, ever since I was linked to this site, I've been enjoying spreading the gospel of
Cake Wrecks - "When professional cakes go horribly, hilariously wrong." There are a few bad Doctor Who-related (and unintentionally related) cakes, lots of misspellings, writing decorating directions as part of the message on the cake ("It's a Girl in pink"), and the has-to-be-seen ("It's Just a Cold Sore!"). Also has a badass Lego Batman game cake.
