This humorous article started out as part of an A level English reference paper and has been added to by friends since then. I do not claim to have written it all, it is listed here purely for your amusement.

SO, YOU THOUGHT YOU WERE TOUGH ENOUGH TO TRY TO LEARN ENGLISH? 
This little treatise on the lovely language we share is only for the brave. Peruse at your leisure, English lovers. 

Reasons why the English language is so hard to learn; 

1) The bandage was wound around the wound. 
2) The farm was used to produce, produce. 
3) The dump was so full that it had to refuse more refuse. 
4) We must polish the Polish furniture. 
5) He could be lead if he would wear the lead. 
6) The soldier decided to desert his dessert in the desert. 
7) Since there is no time like the present, he thought it was time to present the present. 
8) A bass was painted on the head of the bass drum. 
9) I did not object to the object being there. 
10) The insurance was invalid for the invalid. 
11) There was a row among the oarsmen about how to row. 
12) They were too close to the door to close it. 
13) The buck does funny things when the does are present. 
14) A seamstress and a sewer fell down into a sewer line. 
15) To help with planting, the farmer taught his sow to sow. 
16) The wind was too strong to wind the sail. 
17) After a number of injections my jaw got number. 
18) Upon seeing the tear in the painting I shed a tear. 
19) I had to subject the subject to a series of tests. 
20) How can I intimate this to my most intimate friend? 

Let's face it - English is a crazy language. 
There is no egg in eggplant nor ham in hamburger; nor is there apple or pine in pineapple. English muffins weren't invented in England nor were French fries invented in France. Sweetmeats are candies while sweetbreads (which aren't sweet or bread) are meat. 
We take English for granted. But if we explore its paradoxes, we find that quicksand can work slowly, boxing rings are square and a guinea pig is neither from Guinea nor is it a pig. And, why is it that writers write and runners run but fingers don't fing, grocers don't groce, and hammers don't ham? 

If the plural of tooth is teeth, why isn't the plural of booth beeth? 
One goose = 2 geese. So, one moose = 2 meese? Apparently not! 
One index = 2 indices! Two dice = one die!
You can make amends but never just one amend? 
If you have a bunch of odds and ends, and get rid of all of them but one, what do you call it? 
If teachers taught, why didn't preachers praught? 
If a vegetarian eats vegetables, what does a humanitarian eat? 

Sometimes I think all the English speakers should be committed to an asylum for the verbally insane. 
In what language do people recite at a play and then play at a recital? Who ships by truck and sends cargo by ship? Why do we have noses that run and feet that smell? How can a slim chance and a fat chance be the same thing, while a wise man and a wise guy are opposites? 

You have to marvel at the unique lunacy of a language in which your house can burn up as it burns down... In which you fill in a form by filling it out and In which, an alarm goes off - by coming on. 

People, not computers, invented the English language and it reflects the creativity of the human race, which, of course, is not a race at all. That is why, when the stars are out, they are visible, but when the lights are out, they are invisible. 

And so it goes on... 
- Which witch did we talk to?

And there we have it, English at its most perplexing. Of course there is more but you need to do an English course to experience its full potency. Even English, English students have been known to throw up their arms in despair.
