Lol ouryve, I do the pulling faces thing too!
Dh gets very cross when I stick my tongue out at ds1 when he's in another room.
Apparently he doesn't know who's the bigger kid! 
We also have the list of banned tv programmes - all of which are dd's favourites. He also cannot stay in the room if I we are watching anything other than children's tv and will run through trying to cover his eyes and ears at the same time. Bizarrely, Neighbours is excepted from this treatment, so now whenever he asks, I always tell him I'm watching Neighbours. Black and white musicals are also acceptable viewing material - apparently. Of course this can cause issues if ds2 wants to watch something with me, as it means ds1 has to be in another room on his own - and so we go round again. 
His favourite sport is telling ds2 how inferior/babyish/wrong he is. He has unsuccessfully tried to ban pink but this is tad difficult given that my parents bought dd a giant pink dollshouse for christmas and its installed right in the middle of the living room. 
Absolutely nothing Disney is allowed to cross our threshold - oh, except the second hand Jungle Book PS1 game he was given recently, as he's studying the original Jungle Book at school, so that's allowed - aparently. 
He is allowed to play with all of ds2's Lego Starwars stuff, but his has to remain safely on the shelf above his bed and absolutely no-one is allowed to touch it. Ds2 also has to play any games according to ds1's strict rules, which can be tricky, because he hates to lose and will continually change the rules and make up new ones in order to win. This morning it was that he could have free goes for every time ds2 moved when he was throwing his bakugan, as obviously it made the floor vibrate and affected his throwing skills. 
As a family, we are absolutely forbidden from listening to music and GOD FORBID dancing. Dh, dd and ds2 love a good old boogie and like to put some of dh's music on and dance on Sunday mornings - ds1 hates it with a passion. He has a grand total of one album - The Automatic - on the mp3 player he begged for last year, basically because he used to be obsessed with the 'What's that comin' over the hill' song. Apparently its acceptable for him to listen to that occasionally, but all other music "is just stupid, annoying and a complete waste of time". However, we are for some reason, allowed to listen to music in the car.
Interestingly, he also has a big problem with a boy in the year below him at school. I knew this boy had been excluded a couple of times and could be a bit of a handful, but didn't know him personally, iyswim. Turns out, said boy is now working with ds1's ASD Inclusion Teacher - something ds1 was absolutely horrified about when he first found out, because obviously she belongs to ds1 and ds1 alone. He still doesn't like him, but we've had several hundred talks about tolerance/differences etc and it seems this boy is now sort of forgiven because he has AS. They even manage to play on the same cricket team without arguing these days!
