Brain Cupcakes

I signed up to bring cupcakes to my work Halloween potluck. I'm thinking about making ones that look like spiders, ones that look like mummys, ones that look like pumpkins... and I need one more idea. Are brain cupcakes too creepy?

Things to keep in mind:

1. I'm new here
2. I won't know most of the people at the potluck. I haven't met most of the 120 or so people who work in our office building
3. It's Halloween!
