The Lone Ranger - Or 'You Learn Something New Every Day'.

The Lone Ranger and Tonto had been tracking the bloodthirsty bandit Blackheart Bart for five days now.
They crouched in the undergrowth near his hideout, watching the single sentry pacing up and down.
"Well here it is old friend," said the Lone Ranger. "Blackheart Bart's hideout."
"Yes, it is Kemo Sabe." Said Tonto.
"Do you think you can take out that sentry with your bow and arrow?"
"Of course I can Kemo Sabe." Tonto drew his bow, nocked an arrow to the string and took careful aim.
"Remember, don't shoot to kill - we don't work like that." Said the Lone Ranger.
"Of course not Kemo Sabe." With that, Tonto loosed his arrow, which struck the sentry right between his thighs. He collapsed without a sound.
"Great shot!" Said the Lone Ranger. "You got him!"
"Yep," said Tonto. "Right in the Kemo Sabes."
And that, historians determined was the exact moment the Lone Ranger's relationship with Tonto went sour.
