That's an even BETTER analogy! You're on the pot - you're full of cramps so bad that you're think death may just be more pleasant. It's too big to come out - but..... it can't stay in! Hold breath, grit teeth, PUuuuuuuuush! You will flush it all away in the end, but you HAVE to get it out of you - it's toxic.
