The most powerful liquid known to man.

Little Johnny is sitting on the side or the road holding a mason jar of liquid up to the sun when a Baptist Preacher comes walking along.
"Little Johnny, what have you got there in that Mason Jar?" asks the Preacher.
"Oh nothin'. Just the most powerful liquid known to man," replies Little Johhny.
"Oh, no Little Johnny," the Preacher explains. "The Most Powerful liquid known to man is Holy Water. If you rub a dab of that on a pregnant woman's belly, she'll pass a baby boy."
Little Johnny shakes his head and says, "Shit Preacher, this here's turpentine, and my brother says if you rub a dab of this on a cat's ass, it'll pass a motorcycle."
