"To continue, press CTRL-ALT-DEL" joke
A Cyberspace friend of mine here in Istanbul who teaches computer science to junior high-school students related the following (real) occurrence in one of his classes.
It was the early days of the school year and he was describing the machines (PCs) to the kids in general terms. As he was explaining keyboard functions he pointed out that if the computer ever got locked up (he demonstrated a lock-up) you could regain control of the machine by pressing CTRL-ALT-DEL simultaneously (demonstrating that, too).
Some of the kids objected that their hands were too small and that they weren't quick enough to hit all three keys at once.
As the teacher began explaining and demonstrating that all you needed to do was hold down CTRL+ALT with one hand and press DEL with the other, his eye happened on a boy in the front row: He had the index finger of his left hand on the left CTRL key, the index figure of his right hand on the right ALT key and after searching for the DEL key for about five or ten seconds, he paused for a moment as if thinking what to do next and then calmly pressed it with his nose...
