Have you ever called into a radio show?

I listen to the radio daily, but I’ve never called into a talk show. I often feel like I should, but I get nervous or distracted…

If you have called in, what was the show? Did you have to explain your question or comment to someone first before they would let you on the air? Do you feel like you were able to express yourself in the way that you had hoped? Did you change the direction of the conversation?
