How do i get payback on my brother?

I always lo0g out of facebook and when he gets on facebook i am still not logged out so he puts dumb status things on my wall like i put them. one said " i am collecting boogers in a jar i am almost halfway don" or something like that. apparently A lot of people commented on it. its really embarrasing and gross. he is 20 years old. i am 13. girl. i can put status updates like that on his because he is logged on sometimes, but not all the time. when i do the same thing to him, what should i put for his status update? or what should i do to make him angry not on facebook? he is so immature. oh, btw i also deleted the status, but a few people commented on it.
