My MIL G-d rest her soul, wish I could make amends...but for anyone who remembers Italian bakery from the old country...rum cake to die for...seriously. Honey balls at Christmas and there might be a waiting list...
Get a clear stencil sheet from a craft store. Print out an image of Bill Murray in the size that will fit the top of your cake. Tape it to a cutting board and tape the stencil sheet on top of it. Use a sharp craft knife to cut out all of the dark areas on the picture.
