A Joke?

I woke up this morning and glanced at the notice board we have in our room, and noticed there was something new added to it.

Here's what it said:

The preacher said, "Lord, without you we are but dust...", it was then that my friend looked at me and asked, "What is butt dust?"

Without knowing why my husband wrote that up there, its funny, but is it a joke? Has anyone heard of this? or maybe it was a dream he had and wrote down before he went to work.

Who knows, but it's funny :)
