Meatloaf "cake" and Mashed Potatoes "Frosting"

This is something fun I tried after watching Martha Stewart do this on the David Letterman show. It is a "meatloaf cake," frosted with mashed potatoes. The eyes and mouth are cheese. My family enjoyed it a lot, and as Martha said, "This would be great for a children's party to keep the sweets intake down."
Just use your favorite meatloaf recipe and bake in layer pans. Make your mashed potatoes and use your frosting bag and tube to make the edging and "hair" around the edges. Have fun!
