I have a good one that ends with sweet sweet revenge. I was a junior and my brother was a senior in high school. I had a date that night with the hottest cheerleader in school. We came home late and I was trying to sneak her back to my room for sexy time. My brother foresaw this and made sure to coat the tile right inside the front door with a layer of olive oil.

So my date and I are sneaking into the pitch-dark house to get to my room to make fuckie when the both of us bust our asses on the slick tile floor, she of course lets out a high pitched girl-shriek which pierces the deafening silence and wakes the whole house up. I had to stumble through an excuse when my parents came out that she left her lip gloss in my room (haha what the fuck?). I see my brother peering out of the hallway with an evil look on his face as my father tells the cheerleader goodnight and closes the door behind her.

I had a friend at school who sells weird shit, pretty much whatever you could ever need to get high or start a small revolution. One day, don't ask my why, he's selling ghost peppers -- essentially one of the hottest peppers on Earth. My friends are by now all aware of the olive oil incident and we formulate a plan.

One night my parents order Chinese Food for all of us. My brother is upstairs in his room when it arrives so I take my opportunity to exact revenge. I carefully conceal chunks of the ghost pepper in his General Tso's Chicken and mix it all up....then I wait.

He comes down and grabs his food and sits out in the living room. I'm standing at the kitchen sink behind the wrap-around counter that looks out into the living room. I've already poured all the milk down the drain, save for one glass next to me (milk is one of the only things that can neutralize the burning -- think Fight Club) and put the empty milk jug back in the fridge.

Eventually he bites into the instrument of my revenge and moments later is breathing really hard and spitting his food onto the coffee table. He hurls himself off the couch and starts jumping up and down like a maniac going "aggghhhmmmm!!" and runs to the kitchen.

I say "dude, milk! Milk will stop the burning!" He slams into the fridge, opens it up and frantically pulls out the empty milk carton while his eyes go wide as saucers. I calmly deadpan, "oh no, now I'm pouring the last of the milk down the sink" and pour the glass of milk into the running water.

He's jumping from foot to the other now, doing the dance of the completely fucked, while streams of saliva pour from his mouth. I reach up into the cabinet above the stove, grab the bottle of olive oil, toss it to him and say "see if that does the trick mother fucker."

TL;DR -- My brother gets me caught by my parents trying to make fuckie with hot cheerleader, I exact sweet sweet revenge.
