Checking For Tattoos.

"Look!  That caterpillar has spikes in his hair!"  My neighbor's four-year old niece shouted when she spotted this caterpillar on my patio step.  "Hm-m-m, I wonder if it has tattoos?"  I laughed.  Then I posed a question, "Well, if he has spiked hair, he probably has tattoos too.  Right?"    She gave me a blank look, then answered in her little voice, "Maybe his tattoo is on his belly."
