(I've seen some of these, but not all of them. At least one of these statements is not true. Which? Any others?)

Several:

The three most valuable brand names on earth: Marlboro, Coca-Cola, and Budweiser, in that order. [this one is dubious and probably untrue]

A duck's quack doesn't echo and no one knows why. [how this idiotic story stays alive is beyond me]

Elephants are the only animals that can't jump. [obviously false -- turtles can't jump, neither can snails. I think it started out as "the only *mammals* that can't jump," but I doubt rhinos or hippos can either.]

The Main Library at Indiana University sinks over an inch every year because when it was built, engineers failed to take into account the weight of all the books that would occupy the building. [a popular urban legend about many buildings]

Our eyes are always the same size from birth, but our nose and ears never stop growing. SCARY!!!

If Barbie were life-size, her measurements would be 39-23-33. She would stand seven feet, two inches tall. [meaningless. she could be *any* height]

Americans on average eat 18 acres of pizza every day. [only the really fat ones do this]

Marilyn Monroe had six toes.

(Three on each foot?)

Pearls melt in vinegar.

(Not a big suprise....aren't they made from calcium or similar?)

A duck's quack doesn't echo and no one knows why.

(Not loud enough?)

Elephants are the only animals that can't jump.

(Is that "up" or "down"? Many living creatures can't jump "up"....many can jump "down".)

Women blink nearly twice as much as men.

(Ummm........people tend to blink more when they are lying. Not meaning to suggest anything, there.)

No word in the English language rhymes with "MONTH."

(Unless, of course, you tend to lisp.)

An ostrich's eye is bigger than its brain.

(Like Conservative politicians?)

(sig.) If you want to win an argument, it is best to stick to the truth. Or provable untruths.

Apples, not caffeine, are more efficient at waking you up in the morning.

(I think if you had 5 cups of coffee, you'd be more awake than after 5 apples...)

Most dust particles in your house are made from dead skin.

(nah.. complete crap, think about your attic, it's full of dust. how many skinned creatures inhabit your attic???)

"Go," is the shortest complete sentence in the English language.

(what about I. as in:

"who did this to the cat?" "I".)
