Toenails for Breakfast

This morning I was kissing Grant's feet and I notice that his last 3 nails on his feet were long, but the first 2 were not. I asked him if he was biting his toenails and he told me yes. Then he proceeded to show me how he does it. I told him that this was disgusting and he should not be doing that. He replied, "But I love it!" Rotten, simply rotten.
