[BlogEntry] Unboundedly Long Songs

BoingBoing has this story about unboundedly long songs. Not infinite, since you can stop whenever you want, but songs that have no specific end. For instance, X Bottles of Beer on the Wall. You can pick whatever X you want.

I'm surprised that "Old MacDonald Had A Farm" isn't on there. Katherine the other day asked me when that song ends, and I told her it ends when you stop singing. Am I missing something? Does that song have an end that I don't know about?
