Would the need to poop ever be a sermon stopper?

I mentioned in my pre-sermon checklist the importance to poop before you preach. No one wants to be, at worst, uncomfortable while speaking.

But, I wonder what would happen if you were preaching, or leading a church service, and the urge to poop struck?

Sure, I'd hope you'd be able to tough it out (I was going to say suck it up, but that didn't sound quite right). But, what if you couldn't...

What if the feeling was beyond an urge?
Would you stop what you were doing?

Ideally, if you were leading a service then you could just get someone, between service elements, to sub in for you and take over off the cuff.

But, this is far more difficult mid-sermon.

If you're on the verge of a poo explosion ten minutes in?

As a sign of authenticity and genuineness you could just announce your need and duck out for a few minutes.

Alternatively, you could try to grant yourself a communal or spiritual window by asking the congregation to share with the person next to them or prayerfully consider a point for a few moments.

Of course, with these options you run the risk of your absence being noticed and needing to be stealthy in your departure.

From a congregational standpoint, how would you feel if your preacher took a poop break?

Would it be funny?
Would it be awkward?
Would you feel more empathy for the preacher?
Alternatively, would you feel disgusted, offended or removed from a "spiritual" moment?

No matter, one course of action couldn't be for the preacher to poop themselves in the pulpit. 

Surely...
