[The episode starts with Lincoln and Sam reading comics in Lincoln's room.]
Sam: It's quite the day to indulge in crime-fighting violence and witty one-liners.
Lincoln: You said it.
[Just then, they hear Charles barking and Cliff yowling.]
Sam: Psh! That's not going to bother us.
[The two go back to reading. Then, they hear Lana and Lola yelling at each other.]
Sam: [agitated voice] Irritation levels rising...
[Finally, there's a huge ruckus Lincoln's sisters are making outside.]
Sam: Ugh! Can't two guys read about panelized superhero action in peace?!
Lincoln: Ugh. This happens pretty much every day.
Sam: If only there was a way to silence them, or at the very least, drown them out to get some peace and quiet.
Lincoln: I've tried that before. It only ended up in my sisters, besides Lisa and Lily, pranking me in order to [airquotes] "teach me a lesson", instead of talking to me about it.
Sam: What was all of that about?
Lincoln: I ended up being used as a punching bag, a mannequin, an ottoman, and was scared into thinking Lola was going to do something awful to me.
Sam: Man, the nerve of them!
Lincoln: Yeah!
[Lincoln and Sam pout on the bed, until Sam gets an idea.]
Sam: I got it! We'll just have to fight fire with fire.
Lincoln: [confused] Huh?
Sam: By both "fire"s, I mean pranking.
Lincoln: Oh...
Sam: I was thinking along the lines of [clears throat] Operation: Week of the Pranks!
Lincoln: [smiles mischievously] That sounds like a great idea. But, what do you have in mind for said pranks?
Sam: Alright, let's plan it out. [pulls down a big calendar and a finger pointer] We'll start out small on Sunday by drawing goatees on their faces and hide all the mirrors. Monday, we set all the clocks in the house wrong so that they'll miss school entirely. Tuesday, we change the TV channels from the sidelines while they're watching television. Wednesday, we glue their prized posessions to the ceiling fan and make it so that the fan can't be turned off. Thursday, we pour hot sauce into their dinner. And lastly on Friday, we give them surprise gifts from their "secret admirers" Got all of that, pal?
Lincoln: Yep.
[There's a knock at the door, and Lincoln opens it to reveal Lisa.]
Lisa: Pardon me, but I heard you're planning vengeance on my 8 elder siblings for the whole earbuds incident. Correct?
Lincoln and Sam: [nervously] Yes...
Lisa: I want in. I'm normally not one to stoop to pranking any of my siblings, but in this occasion, I'll make an exception since they fired first.
Sam: Great! Welcome aboard.
Lincoln: Now, it's time to put Operation: Week of the Pranks into action!
