Girls and ladies, some help please?

sorry this is random. i'm 14 and my 13 y.o. brother "pantsed" me today in front of my mom. he's so annoying and it's not the first time he's done it. in the past my mom's grounded him and stuff like that. this time, though, she said she would take away his phone for one day OR she would make him do one of my chores naked - to give him a taste of his own medicine. it's my choice. what do u think? and if you go with naked chores, what would u have him do? i was thinking clean behind the couches, b/c to do that he'd have to straddle them, and u know what that means (lol, nut crunch). but wut do u think? help me out, girls!!!
