A preacher walking down the sidewalk sees a little boy playing
with a a little bottle of turpintine. The preacher says "Well,
hello there son, what have you got there?". The little boy says
"This here sir, is the most powerful liquid in the world.". The
preacher looks at the bottle and says "Oh no son, that cannot
be the most powerful liquid in the world. The most powerful
liquid in the world is holy water. If you take a couple of drops
of holy water and rub it on a pregnant woman's belly, she'll
pass a baby girl.". The little boy thinks about this for a
minute, perks up and says "Well ah heck, that ain't nothin. You take
a couple of drops of this and rub it it on a cat's ass and it'll
pass a motercycle!".
