A short list of things that might be classified 'worldwide humour' that I find amusing.
Once upon a time there was an email going around that had a fun take on the English language. It also showed how you can take one language (this arguably applies to everything in this world) and find similarities with another. The text transitions from English to German with what I might call a plot to change the international language from English to German (and I suppose that is why some take offence - maybe they think that it could have been that way if World War 2 ended with the Axis Powers being 'victorious'?). In fact, it might be said that English BECOMES German (or rather it's more Germanic, a mixture of English and German)!
The European Commission has just announced an agreement whereby English will be the official language of the EU rather than German which was the other possibility. As part of the negotiations, Her Majesty's Government conceded that English spelling had some room for improvement and has accepted a 5 year phase-in plan that would be known as "Euro-English".
In the first year, "s" will replace the soft "c". Sertainly, this will make the sivil servants jump with joy. The hard "c" will be dropped in favour of the "k". This should klear up konfusion and keyboards kan have 1 less letter.
There will be growing publik enthusiasm in the sekond year, when the troublesome "ph" will be replaced with "f". This will make words like "fotograf" 20% shorter.
In the 3rd year, publik akseptanse of the new spelling kan be ekspekted to reach the stage where more komplikated changes are possible. Governments will enkorage the removal of double letters, which have always ben a deterent to akurate speling. Also, al wil agre that the horible mes of the silent "e"s in the language is disgraseful, and they should go away.
By the fourth year, peopl wil be reseptiv to steps such as replasing "th" with "z" and "w" with "v". During ze fifz year, ze unesesary "o" kan be dropd from vords kontaining "ou" and similar changes vud of kors be aplid to ozer kombinations of leters.
After zis fifz yer, ve vil hav a reli sensibl riten styl. Zer vil be no mor trubl or difikultis and evrivun vil find it ezi to understand ech ozer. Ze drem vil finali kum tru! And zen ve vil tak over ze world!
