An old man complains that they had better water or glasses in the good old days.
In communism, either the glass or the water doesn't arrive.
An East German checks the glass for listening devices.
A West German refuses to drink the water, because he claims that it is a socialist drink.
An Alcoholic looks at it for a while, then starts to cry.
A Computer game critic writes a review on the glass, claiming that it's too reflective and that it's bloom is completely unrealistic. Then he writes a review on the water.
A Dictator tries to take it over.
A good diplomat negotiates for glass to be filled. After 8 hours and an impressive amount of arguments, the glass is filled.
A bad diplomat negotiates for the glass to be filled. 8 hours later, the glass is empty and the diplomat is fired.
If you ask someone who is a fan of the movie "A few good men", he shall respond saying "You want Anwsers? You want to know the truth? You can't Handle the truth!"
In my opinion the glass is not full enough, but not quite empty either.
