I'd appreciate any hints 'n tips on how to deal with these people.
Ok, here is what I suggested to someone in a different thread, I've modified it slightly for your benefit
Lose to one of them, keep trying to beat him, but 'lose' every time. I know it's usually hard to lose to them, like literally hard, but it will be easy for this time, because you're going to try to 'ass fight' too. So lose a bunch, and then shower them with praise, telling them that they are Jedi Knight gods. Then request to become their apprentice. Spend a lot of time learning the ways of the ass fighter, befriend the ass fighter.
Then, get him to tell you where he lives. Once he's told you, go to his house and use a garden hose to soak him, and his PC.
