I knew some of those were incorrect, so I did a little research...

"Stewardesses" is the longest word typed with only the left hand and "lollipop" with your right.

There are several longer. For example “sweaterdresses” has 14 letters typed with the left hand, and “polyphonous” has 11 letters typed with the right hand.

No word in the English language rhymes with month, orange, silver, or purple.

Here are a few I found searching around: A "sporange" is a sac in which spores are produced… a "chilver" is a ewe lamb, and a "hirple" is a a British term meaning to hobble or walk lamely.

"Dreamt" is the only English word that ends in the letters "mt". (Are you doubting this?)

Yes, I'm doubting this… "undreamt" and "daydreamt" also end in "mt".

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

Not correct. At birth, the human eye is roughly 2/3 of the size it will be in adulthood.

The sentence: "The quick brown fox jumps over the lazy dog" uses every letter of the alphabet. (Now, you KNOW you're going to try this out for accuracy, right?)

The words 'racecar,' 'kayak' and 'level' are the same whether they are read left to right or right to left (palindromes). (Yep, I knew you were going to "do" this one.)

There are only four words in the English language which end in "dous": tremendous, horrendous, stupendous, and hazardous.

Here are some other ones: Podous, iodous, iridous, jeopardous, molybdous, phyllocladous, vanadous.

There are two words in the English language that have all five vowels in order: "abstemious" and "facetious."

Here are some more: Caesious, arsenious, acheilous, aerobious…

TYPEWRITER is the longest word that can be made using the letters only on one row of the keyboard. (All you typists are going to test this out)

Typewriter has 10 letters, as do pepperwort, pirouetter, proprietor, repertoire, repertory…

A cat has 32 muscles in each ear.

A cat’s ear contains no muscles, though it is connected to many, the actual number depending on the species of cat.

February 1865 is the only month in recorded history not to have a full moon.

Not true… the last time this happened was February, 1999. The next one will be in 2018.

In the last 4,000 years, no new animals have been domesticated.

Not true… the Hamster was domesticated in the 1930’s, the ostrich in the 1800’s just to name a couple.

If the population of China walked past you, 8 abreast, the line would never end because of the rate of reproduction.

Not true… Here’s an explanation by one expert… "The current population of China is about 1.25 billion, with about 20 million births per year. We'll assume that the birthrate stays about the same, as the population grows a bit but the births per 1000 drops a bit, under the current one child per family policy. The Chinese walk say 3 feet apart at 3 miles per hour, for a rate of 46 million Chinese per year. So even if no one died in line, the line would shorten by 26 million per year and run out in about 1250/26 = 48 years."

Leonardo Da Vinci invented the scissors.

Scissors were invented around 1500 BC in ancient Egypt, about 3,000 years before Da Vinci was born. (Wikipedia)

There’d better be… I eat several myself each year and I wouldn't want to contribute to their extinction.
