I don't think this is the most pleasant way to be introduced to rationality, but irrational behavior as a teaching device has worked surprisingly often for me.
Most of the rationalists I know are self taught, and the reason they became interested in avoiding bias and fallacies in the first place is almost universally that they got tired of ridiculous arguments with someone else who was using them and began looking for rules that forced thought processes to stay a bit more sane.
Nobody I know appreciates being shown flaws in their own arguments, but if you advocate that we should stop using fireplaces on Christmas eve to protect Santa (for example), then sooner or later most people will come up with a good reason why your argument is irrational. When they come up with the rule on their own and you concede defeat, the rule is marked as a way to win arguments, not a tool other people can use to disprove my own ideas.
And once someone accepts that thoughts can be flawed and knows how to identify them, it is a hard habit to break. Each fundamental idea that helps you think rationally is slightly more easy to accept then the last one, even if actually applying them without help is still difficult.

Is this an actual example you used? Who would bother rebutting it?
After his wife died, Elzéard Bouffier decided to cultivate a forest in a desolate, treeless valley. He built small dams along the side of the nearby mountain, thus creating new streams that ran down into the valley. Then, he planted one seed at a time.
After four decades of steady work, the valley throbbed with life. You could hear the buzzing of bees and the tweeting of birds. Thousands of people moved to the valley to enjoy nature at its finest. The government assumed the regrowth was a strange natural phenomenon, and the valley's inhabitants were unaware that their happiness was due to the selfless deeds of one man.
This is The Man Who Planted Trees, a popular inspirational tale.
But it's not just a tale. Abdul Kareem cultivated a forest on a once-desolate stretch of 32 acres along India's West Coast, planting one seed at a time. It took him only twenty years.
Like trees in the ground, rationality does not grow in the mind overnight. Cultivating rationality requires care and persistence, and there are many obstacles. You probably won't bring someone from average (ir)rationality to technical rationality in a fortnight. But you can plant seeds.
You can politely ask rationalist questions when someone says something irrational. Don't forget to smile!
You can write letters to the editor of your local newspaper to correct faulty reasoning.
You can visit random blogs, find an error in reasoning, offer a polite correction, and link back to a few relevant Less Wrong posts.
One person planting seeds of rationality can make a difference, and we can do even better if we organize. An organization called Trees for the Future has helped thousands of families in thousands of villages to plant more than 50 million trees around the world. And when it comes to rationality, we can plant more seeds if we, for example, support the spread of critical thinking classes in schools.
Do you want to collaborate with others to help spread rationality on a mass scale?
You don't even need to figure out how to do it. Just contact leaders who already know what to do, and volunteer your time and energy.
Email the Foundation for Critical Thinking and say, "How can I help?" Email Louie Helm and sign up for the Singularity Institute Volunteer Network.
Change does not happen when people gather to talk about how much they suffer from akrasia. Change happens when lots of individuals organize to make change happen.
