Forget it, Ilan. I have no chance against my son and he taunts me all the time. Sits down with one of my basses (preferably a Jazz Bass), puts on the most horribly trebly sound imaginable and then plays really close to the bridge something ultra-fast and smiles insolently at me: "Hey, Dad, look, that is bass playing!" To add insult to injury, he then slaps on the bass, something I can't do either.
Edith is very helpful too: "He's quite a bit faster than you, isn't he?"
I get even with chordal things though. "Play a D Sus 9 for me, son!" And he goes: "A what?!!!" And then the stern father: "Haven't you been playing guitar long enough to know a beginner's chord like that?"
