Mosquitoes are attracted to people who just ate bananas
False. They might be attracted to the sweet scent of fruits, but there's no evidence showing that having eaten a banana will necessarily attract mosquitoes.

Cats have over 100 vocal chords
False. Mammals generally have two vocal cords, one on each side of the larynx.
Termites eat through wood two times faster when listening to rock music!
False. I'd bet money this one is made up. Couldn't find a single scientific journal or site that had anything to say about it. Still, it's not ridiculous to think that noise or vibration might affect their behavior, so I guess it might be up for grabs.
The average human will eat an average of 8 spiders while sleeping
How do you think they measured that spider one?
False. tmw's defintely right here, this is definitely a myth.
Frogs cannot swallow with their eyes open
False. Ah... in fact, they both can and do swallow with their eyes open. "Most anurans retract and close their eyes repeatedly during swallowing." (anurans are frogs/toads).

True. This is true. Ultrasound is any sound with a frequency of 20,000 Hz or higher. The upper range of a cat's hearing is around 60,000 Hz.

Giraffes have no vocal chords
False. Though it might seem logical considering they don't really make sounds, giraffes do indeed have vocal cords. "Despite possession of a well-developed larynx and a gregarious nature, the
giraffe is able to utter only low moans or bleats."
(From the abstract of a paper titled "BIO MECHANICS OF THE GIRAFFE GIRAFFA-CAMELOPARDALIS LARYNX AND TRACHEA" by the Institute of Laryngology and Otolaryngology in London.)
"The energy of a discharge of an electric eel could start 50 cars." (Start, but not drive, I bet)
False. It has the voltage. An average car ignition, like
this one (PDF file), generally has a voltage of around 12 V (though it can be more or less). Electric eels can discharge 500-600+ V. Which is around 50 cars indeed.
edit: However, as HeadISBAgent pointed out a couple posts down, it does not have the current needed to start a car (see my post after his for links). An eel can provide 1 ampere, but it takes about 200 to start a car.
"On some Caribbean islands, the oysters can climb trees." (What..the...****!? Yeah, right...)
True. This scientific article (warning: LONG .pdf file) talks about a bivalve called Enigmonia aenigmatica that climbs mangrove trees. It's a type of oyster. So I wouldn't doubt that there are oysters in the Caribbean that can do the same.
This concludes yet another episode of
Gold's Fact or Fiction.
By the way I need to thank you all for this, although I dislike incorrect facts, this thread is forcing me to keep my knowledge and research skills sharp even while not in school. I love it.
