Brother stuff - please answer?

Hi guys, my brother has been pranking me a lot lately, I'm looking to get him back. Any ideas on how I can torture him? (obviously nothing painful or anything, just something to get him back)
I do Taekwondo, so I was thinking of making him lick my sweaty gear, or making him sniff the inside of the bag for 20 minutes.. I could make him dress up in girl clothes (i am older than him + he won't tell), perhaps, my sister has girl school uniform that I could force him to dress up in? Maybe do a little dance? He also hates foods like cheese, I have some cheese sandwiches from school, that are left from Friday, cheap grated cheese in white bread, maybe I could make him eat them, or stuff them in his mouth while he sniffs my fight gear? Any other ideas welcome too. Know this sounds like a weird thread. Thanks, Jack.

Btw please nothing brutal or painful, just something to embarrass or intimidate him a bit. He is 12 and I am 15.
