If you show me
That, say, homeopathy works,
Then I will change my mind
I’ll spin on a fucking dime
I’ll be embarrassed as hell,
But I will run through the streets yelling
It’s a miracle! Take physics and bin it!
Water has memory!
And while its memory of a long lost drop of onion juice is Infinite
It somehow forgets all the poo it’s had in it!

You show me that it works and how it works
And when I’ve recovered from the shock
I will take a compass and carve Fancy That on the side of my cock.

Tim Minchin, Storm

Dammit, how do you get line-breaks? It's a poem, but the stanzas get flowed into paragraphs.
