Mold? That reminds me of a joke.

Mamma mole, papa mole and baby mole lived in a hole outside of a farm house. Papa mole stuck his head out of the hole and said, "Mmmmm, I smell sausage." Mama mole reached her head out of the hole and said, "Mmmm, I smell pancakes." Baby mole tried to stick his head outside the hole, but couldn't because of the two larger moles. Baby mole said, "The only thing I can smell is molasses."
