Well I thought it would be interesting to make one, with a twist. What could be better than to have the "sacrificial" lamb made out of red-velvet cake? It would be so much more gory.
So I set out to find a pan. Never having done this before, I wanted to find a cake mix. I didn't want to go through all the trouble of making a cake from scratch and have it it get screwed up because I did something wrong with the pan. We couldn't find red-velvet, but we did find strawberry swirl - yellow cake with strawberry goo you can swirl into the mix. That sounded like a plan because we could have a gooey spine going down the center of the cake.
This is my (surprisingly) very successful attempt at making a lamb cake and the story of his violent demise:

Fresh baked lamb.
By the way, the apron says "D.A.R.E. to keep presidents off Peruvian Blueflake." I don't get why I'm the only one that finds that funny. John says because it's too specific, but I really think that anyone who thinks about it for a second can put "Peruvian Blueflake," the smirking head of Dubya, and rumors of Dubya's suspected bouts with cocaine together and assume that it's a type of cocaine. I never heard of it before I got the apron either.

The little lamb gets his wool (whipped cream frosting). I had to go all out on this. I got a decorating set and everything. I took a cake decorating class when I was about 10, and it kinda came back to me. Yeah, yeah, shut up. I took a cake decorating class. Wanna make something of it? By the way, the secret to getting the two halves to stay together - royal icing - it dries hard and acts like glue. Don't frost the whole thing in that stuff though - it tastes like wallpaper paste.

He knows something terrible awaits him. I love the way he looks from the side. He knows he isn't long for this world. The googly eyes were John's idea.

The sacrifice: Yes, a bit overly dramatic. But if you're going to have a sacrifice, I say do it right.

Off with his head: Kinda speaks for itself.

The chewy center revealed: The strawberry core worked very well. His head just kinda plunked right down on the plate, it was great.

John said it looks like lungs. Next year, I'm doing red velvet - imagine how much more gorey that would be than yellow cake dyed pink. The chewy center is staying though. Maybe raspberry preserves. I'll have to think about that.

Whoever bakes it gets the head. No, I didn't eat the googly eyes. He was actually quite tasty.
I think he turned out rather well, and it gave me an excuse to figure out how to post pictures to this damn blog.
