Songs to entertain as one waits

I can imagine watching this one while laying back in a dentist's chair...

So far today I got down to as low as 28 minutes and then my wait jumped back up to over an hour. Then it went to 49 minutes then back to over an hour again. It almost always does that. One time it seemed like it was working the way it should and I went down to four minutes and then when it was my turn, it just said that no agents were available and it timed out.
