Do you really want to know how I learned what one is? In Snow White and the Seven Dwarfs! In the song and dance segment, one of them sings (or is more like today's rap) something about a "polecat chased me up a tree". So, I looked it up. LOL!!!! I used to think it was a skunk before that! See, watching movies with my kids when they were little wasn't a complete waste of brain time!
