Approaching the bridge, Sir Lancelot the brave agreed to be the first to face the bridgekeeeper's questions, as Sir Robin, the Not-Quite-So-Brave-As-Sir-Lancelot didn't have as much courage. The bridgekeeper turned out to be the same old man who once led them to Tim the Enchanter and he asked Lancelot these questions:
Bridgekeeper: What is your name?
Lancelot: My name is Sir Lancelot of Camelot.
Bridgekeeper: What is your quest?
Lancelot: To seek the Holy Grail.
Bridgekeeper: What is your favourite colour?
Bridgekeeper: Right. Off you go.Of course, Lancelot managed to cross the bridge, and, seeing how easy the questions are, Sir Robin eagerly went second. His first two questions were the same as for Lancelot- but the third wasn't as easy: what is the capital of Assyria? Robin, startled, said that he doesn't know, and a moment later he was thrown into the gorge with a scream. Sir Galahad, the chaste, went third. His questions were all the same as for Lancelot- but when he answered the same as Lancelot, saying that his favourite colour is blue, he then quickly tried to correct himself and say yellow, but that didn't save him from being thrown into the chasm for his small mistake. King Arthur was the fourth- the first two questions were the same as for Lancelot, Robin and Galahad, but the third was: "What is the airspeed velocity of an unladen swallow?" Arthur asked which kind of swallow: African or European, and when the bridgekeeper answered "I don't know that", he was thrown into the gorge himself.
After this, Arthur, and the last knight, Sir Bedevere, the wise, crossed the collapsing, old Bridge of Death without any more questions.
