Why call it a shower?

I'm not exactly sure where the quote comes from, but i had heard once that this guy, possibly a preacher of sorts said "Some of the best sermons I have given have been in my own shower."

I'm not professing to be a preacher or having anything of value to say.

If I had the time to monitor comments, i might consider it. Basically, if I wanted to read any comments, I'd find your dribble on the web and read it.
