Serious Then Not

I went confession yesterday. I try to go on a regular basis; it is good for the soul. It forces you to reflect on life, what you shouldn't have done, what you should have done, what you could have done better and so forth. 

But enough of that seriousness. I noticed when I arrived that the entire waiting room was nothing but men. All men, waiting for confession.

So, ladies, I give this to you. What's the punchline?
