What did Sir Kay tell Sir Ector about the sword?

Sir Kay told Sir Ector that the sword was placed into the anvil and that: Whoso Pulleth Out This Sword of the Stone and Anvil, is Rightwise King Born of All England. Kay is certain that it is him, but Wart later pulls it from the stone in an act of haste. Kay tries to take credit for pulling the sword from the stone, but when he's asked to repeat the act, he confesses and falls down before Wart.
