Cheer Me Up, Please

I have a backache and not enough work to do right now.
While I have faith I will soon have fresh new assignments and projects to work on, today I am feeling a little puny and need to laugh.
It's drizzly and chilly outside, so that's not helping, either.
Tell me a joke or a funny story.
The winner gets a Blog full of haiku, all about them or any subject they request.
