How to Get Revenge [Prank]?

This all started Yesterday me and my big bro Were plain Basketball We made a deal who ever loses has to get kicked in the balls. Ii won so i was contain down the kick him in the balls 3.2.1. then he quick and swiftly gives me a hard punch right to the balls like it didn't even touch my wiener it hit exactly my balls [hurt like heck] after about 6 mins i Healed my self and [no homo] gripped his nuts tightly Ii knew Ii could damage him severely so I didn't grab REALLY tight and I Only held on for like 15 seconds. So later that night we were all in the house Me and my good friend james and his 2 friends Kevin and Isaac I had A full glass Od ginger-ale But It was my day to take the trash out so they all had pissed in my cup of ginger-ale and when I Came back I took a sip and Immediately Spit it out cause of the false taste. I wasn't really expecting that prank so I didn't have good revenge all I Did was pour about of gallon of mud on him while he was showering. So the next morning He gathered all the poop he could find even my 2 dogs poop. He blended it all together and poured it on me then he took a poopy diaper from my little cousin alex and strapped it on my face then put duck tape on the back and smeared it all over my face. So I really need a Good Very good prank to get him back with.
