Some useless knowledge to show off a bit...

Info copied and edited, with my comments in brackets:

Knowing your keyboard:

‘Stewardesses' is the longest word typed with only the left hand. (I am taking his word for it)
And 'lollipop' is the longest word typed with your right hand. (same with this and other similar statements)

'TYPEWRITER' is the longest word that can be made using the letters only on one row of the keyboard.

The sentence practised by secretaries under training since umpteen years ago: 'The quick brown fox jumps over the lazy dog.' uses every letter of the alphabet. (Cheng used to be amazed by my ability to type without looking at the keys, now she knows)

The average person's left hand does 56% of the typing. (wonder who did the research, why, and how true this is!)

Useless info on English (because you won’t be tested and therefore will not get an A for knowing them):

No word in the English language rhymes with month, orange, silver, or purple.
'Dreamt' is the only English word that ends in the letters 'mt'.
The words 'racecar,' kayak' and 'level' are the same whether they are read left to right or right to left (palindromes).
There are only four words in the English language which end in 'dous': tremendous, horrendous, stupendous, and hazardous.
There are two words in the English language that have all five vowels in order: 'abstemious' and 'facetious.'

Common mistake: Q.E.D. It is 'quod erat demonstrandum' which means 'that is what I wanted to prove and I have proved it.'.
. and not 'Quite Easily Done’.

Facts and fancies (aka useless info):

Our eyes are always the same size from birth, but our nose and ears never stop growing. (only our eyesight deteriorates over time; our nose because of the lies we had to tell now and again, while the ears because of our increasing nosiness)
A cat has 32 muscles in each ear.
A goldfish has a memory span of three seconds. (and that is considered better than mine!)
A 'jiffy' is an actual unit of time for 1/100th of a second. (so don’t believe anyone who said 'will be with you in a jiffy')

A shark is the only fish that can blink with both eyes. (wonder what difference does it make to us, or how can we tell without getting near to them and survive?)

A snail can sleep for three years. (who was it who bothered to find out? How did he do it?)
Almonds are a member of the peach family. (that does not explain its bed bug smell)

An ostrich's eye is bigger than its brain. (no wonder it has yet to figure out how to fly)
Babies are born without kneecaps. They don't appear until the child reaches 2 to 6 years of age. (no wonder they either crawl or walk differently!)

In the last 4,000 years, no new animals have been domesticated. (no wonder househusbands feel lonely like hell)

If the population of China walked past you, 8 abreast, the line would never end because of the rate of reproduction.
(thank God, it was never done on their National Day)

Leonardo Da Vinci invented the scissors. (because he needed to trim his beard or brushes?)
Peanuts are one of the ingredients of dynamite! (Jimmy Carter has a lot to answer for that, and that’s why he is a peace-maker now)
Rubber bands last longer when refrigerated. (not music bands for sure, but not sure about contrabands)
The cruise liner, QE 2 moves only six inches for each gallon of diesel that it burns. (no wonder they calculate in terms of gallons per mile!)

The microwave was invented after a researcher walked by a radar tube and a chocolate bar melted in his pocket.
(it happened to many people but they didn’t realise the importance!)

The winter of 1932 was so cold that Niagara Falls froze completely solid. (for sure I would not stand on it)
There are more chickens than people in the world. (or is it there are more people who are chickens?)

Winston Churchill was born in a ladies' room during a dance. (that’s why he tried so hard to be macho?)

Women blink nearly twice as much as men. (They were actually winking but could not do it properly)
