What to do with a six year old annoying brother who plays on the 360 every day?

Gawwww! He's sort of annoying (sorry mom, dad, and Bran if you're reading this). He sits in front of the T.V. every single day and plays a stupid robot game. And he thinks the video game I play, Oblivion, is boring and he makes fun of it! And if he does anything bad to me, he'll try and bribe me (he got it from me). Please help!
