One day, somebody opened up the shell of an oyster and found inside what appeared to be a large globule of phlegm. But instead of throwing it away, he ate it. And he discovered that it was not only delicious, but also, that it was an aphrodisiac. Well I have the same amount of respect for the man who looked at his remote-controlled car and said "I know, I'll armour-plate that and use it to bash into other armour-plated remote-controlled cars". it may not have resulted in an urgent need to have sex, but he had invented Robot Wars.
