More and more, as Lucas revises and changes the Star Wars past, I'm convinced the Jedi are the worst at a lot of things....
"He's the chosen one! The chosen one! Well, unless the prophecy misread, it was!"
"He's too old to learn the ways of the Jedi - but let's teach him anyway! If we - I mean if HE, all by himself with no responsibility on our part - screws it up, we'll just go through the whole thing again 20 years later with his kid; gotta get right back on that horse, after all...!"
"All the Jedi have been killed!! Let's send out the secret signal to bring them back in now smaller numbers to the temple when the Jedi killer army is!!!"
"No, let's NOT send the Jedi back to the temple where the Jedi killer army is!!"
"The Force is a religion! No, it's biology!"
"Your father wanted you to have this light saber when you were old enough.... although he never actually told me that, and in fact thought your mother had died while you were still inside her. Anyway, he was killed by some completely other person....well.... from one's point of view, that is!"
"Emotions and passion are the way of the Sith! Wookies are known to pull arms out of sockets when they loose! Wookies = Sith! Who's side is their army really fighting on?!"
"Kid, I've been from one side of the galaxy to the other and never seen an all-powerful Force - & note that my Wookie companion has nothing to say to contradict me on the matter, even though he himself saw Jedis in battle!"
"What? A Sith Lord right here in front of us? And a lot of his friends in front of us? And Jedis deciding to quit the order, and we're not even keeping tabs on them? Kenobi, when you go into hiding, I hope you can hide as good as The Emperor does!"
"ONE of us Jedi masters ordered an entire clone army - and none of you other Jedi masters knew about it? What "master" is in the accounting office?"
"Let's give children laser swords!"
"We'll have a democracy - and have a queen lead it! Hey, I know: a queen with term limits, yeah!"
"The Sith master can only have one apprentice.... but he can keep replacing them! Hey - it's still only 'one'!"
Apparently, Jedi's greatest weaknesses are plot logic and continuity.
