im gonna be honest and said i laughed. but that was also really mean

Pwned

your sister must have thought that was really funny but it is just messed up and who voted ydi he is deaf people

that's gonna be hard to top. iv wanted to try this, though. put a boluion(sp?) cube in the shower head in her bathroom. wait for a hot shower from her, and enjoy the soup smell. OR what you can do is take your lights for the doorbell and put like a brighter bulb in hers, then at night ring the doorbell. I dunno. your sister sounds awesome. I wanna hear all these pranks.

oh poor thing! thats horrible...thats not sense of humor, but evil!... =((

Like others said, since her prank worked because you were deaf, get one that works because she can hear, such as a shitload of alarm clocks hidden in her room, set to go off in 3 minute intervals.

Take a long, narrow potato (one that will fit well into an exhaust pipe) and drill a hole in it long ways. Then rig a whistle in one end or find one of those long, thin whistles and stick it in the potato hole. Potato goes in the tailpipe. When the victim gets in the car and starts it up they'll wonder where the hell that noise is coming from. the noise wont bother you at all =] or you can buy an autopipe whistle at a gag store

Well i don't find that most of these people are sitting here thinking about the actual FML rather than arguing back and forth between each-other over their opinions. (therefore, making this a contradictory comment.) i think it was clever and funny, depending upon the age of you two. If you're older it's easier to understand the humor. Kids can be cruel either way, but i respect the good judgement on your part. As long as you know your sister is kidding, this could end up being a great prank-war, and, to top it off, even if it's 'just a prank war,' they too can be FML moments. Get her back as you said you would but be clever.

LMFAO!!!! oh man that is priceless, i say thats fair play though! i mean no offence but she is using your weaknesses against you really well, you had better get her back good!! Lol gotta love sibling rivalry!!

Lmao. Thats amazing. You gotta love pranks :P
