To post some of the more hilarious moments...
Seeing the windmills, mistaking them for giants, Don Quixote says:
"Fortune is directing our affair's even better than we could have wished: for you can see over there, good friend Sancho Panza, a place where stands thirty or more monstrous giants with whom I intend to fight a battle and whose lives I intend to take; and with the booty we shall begin to prosper. For this is a just war, and it is a great service to God to wipe such a wicked breed from the face of the earth."
"What giants?" said Sancho Panza.
"Those giants that you can see over there", replied the master, "with long arms: there are giants with arms almost six miles long."
"Look you here," Sancho retorted, "those over there aren't giants, they're windmills, and what look to you like arms are sails - when the wind turns them they make the millstones go round".
Undeterred, Don Quixote charges headlong at the 'giants' and drives his lance into one of the arm's sails. The wind pushes the arm "with such violence that it smashed the lance into pieces and dragged the horse and his rider with it." Throwing Don Quixote to the ground.
"For God's sake!" said Sancho. "Didn't I tell you to be careful what you were doing, didn't I tell you they were only windmills? And only someone with windmills on the brain could have failed to see that!"
Don Quixote explains that the enchanter Freston changed them from giants to windmills as soon as he began his attack... only to deprive Don Quixote of the glory of victory.
Moments later they see two Benedictine friars on the road, and trailing behind them (though not associated with them) were 4 or 5 horsemen escorting a coach that carried a Basque lady on her way to Seville.
"Either I am much mistaken or this will be the most famous adventure ever witnessed; for those black figures over there must be and no doubt are enchanters abducting a princess in that coach, and I must redress this wrong to the utmost of my power."
I love this response from Sancho:
"This will be worse than the windmills," said Sancho. "Look here, sir, those there are Benedictine friars..."
