Yes, indeed. ;-) I do exactly the same thing. To be able to laugh at one's own little hypocrisies and arrogant tendencies when one catches them in the act is the first good step to understanding and getting along with other people, in spite of whatever shortcomings they may seem to have. As you say, "one needs to be in touch with one's inner 'twat'".

I enjoy playing out stories with various fictional characters like Chongo Chimp in order to demonstrate the amusing and often very predictable behaviour of people who have some good qualities (and Chongo does)...but who also have some major blind spots in certain areas too which can cause them to be quite unreasonable at times. You can't just sum up these characters as "good" or "bad", because they are a confusing mixture of both.

Chongo is loyal, courageous, determined, hard-working, and very independent. This is good. He's extremely outspoken. That can be good...or it can be bad...depending on what's going on. He detests prejudice against apes and monkeys...yet he is himself extremely prejudiced against most apes and monkeys because he thinks chimps are way better than all the others! He's very upset by human prejudice against apes and monkeys, but he's equally prejudiced against humans. Most of the time Chongo is relatively unaware of his "inner twat", but now and then he experiences a moment of real clarity, and realizes that he has been behaving like a total jerk. He is then quite capable of admitting to his own foolishness and is genuinely apologetic about it. He tries to make amends.

This makes Chongo quite likeable in my opinion. He may be a rough diamond, but there is some real value there.
