Huh?

I need to ask a question Does anybody know Who made up these crazy sayings Like walking to and fro They say it sales like hotcakes Do hotcakes really sell They call a skunk a polecat Is that something to do with smell Stick it where the sun don't shine What's that supposed to mean Or a great Idea is always heard But very seldom seen A penny saved is a penny earned Well, how are you gonna eat Or I've never met a person I didn't wanna meet So, if you know this answer Somebody let me know Until then, I'll be waiting Just walking to and fro
