JELL-OH NO, YOU DIDN'T!, "Pilot" (1.1)
Jim puts Dwight's stapler in a mold of jello, an homage to the original BBC series.
PRACTICALITOUS-JOKITIS, "Health Care" (1.3)
Dwight: Someone forged medical information, and that's a felony.
Jim: OK, Whoa, all right 'cause that's a pretty intense accusation. How do you know that they're fake?
Dwight: [reading from a sheet] Uh, Leprosy, Flesh Eating Bacteria, Hot Dog Fingers, Government Created Killer Nano Robot Infection.
THE NICKELER!, "Conflict Resolution" (2.21)
No one can truly appreciate the magnitude of Jim's high jinks until taking a look at Dwight's complaint files. Jim boasts an impressive rap sheet: he's paid off his coworkers to call Dwight "Dwayne,'' replaced Dwight's pens with crayons, put a bloody glove in Dwight's desk and tried to convince him he was a murderer. But perhaps the most elaborate prank in the hefty complaint file is Jim's alleged tampering with Dwight's telephone handset. Jim is charged with incrementally increasing the weight of Dwight's phone with nickels, and then abruptly removing the change. The result? Dwight nailed himself in the face with his phone.
FAX FROM THE FUTURE, ''Branch Closing" (3.7)
My all-time favorite prank! At the new branch, Jim sends Dwight faxes using Dwight's stationary, and he signs them "Future Dwight." After receiving one fax, Dwight jumps on Stanley to save him from a poisonous cup of coffee.
From: Future Dwight
Subject: Office coffee
Dwight: At 8 a.m. today, someone poisons the coffee. Do not drink the coffee. More instructions will follow. Cordially, Future Dwight
VENDING MY STUFF, "Booze Cruise" (2.11)
Jim puts all of Dwight's desk belongings in a vending machine, including Dwight's wallet, which means he can't even buy back his own stuff. Jim hands him a back of nickels, and we're left watching Dwight buy his stuff back one nickel at a time.
FRIURSDAY, "Performance Review" (2.8)
Jim and Pam talk about the day like it's Thursday, even though it's really Wednesday.
Pam: [trying to make Dwight think that it's Friday] Hey, did you watch The Apprentice last night?
Jim: Yeah, I can't believe who they kicked out!
Pam: Oh, I know!
Dwight: Damn it! I missed it! I was out drinking with my Laser Tage Team, I can't believe I did that! I never go out on Thursday nights.
DWIGHT-SQUARED, ''Product Recall" (3.20)
Jim comes to work dressed as Dwight. With a pair of $4 drugstore glasses, a tie from the Salvation Army, a short-sleeve button-up shirt, a calculator watch, and an unfortunate hair part, you too can become a Dwight look-alike! To be even more convincing as a Schrute, be sure to ask a series of nonsensical questions.
PAVLOV PRANK, ''Phyllis' Wedding" (3.15)
Inspired by Pavolov's prank, Jim conditions Dwight to ask for an Altoid at the sound of a computer login bell.
YES, DWIGHT, THAT IS THE REAL BEN FRANKLIN, ''Ben Franklin'' (3.14)
In one of my favorite episodes, Jim hires a Ben Franklin impersonator to be a stripper for Phyllis's bachelorette party. Dwight tries to catch Ben Franklin in a lie and is 99% sure it's not the real Ben Franklin.
Dwight: Far-sighted or near-sighted?
Ben Franklin: Both. I invented the bifocals.
GAYDAR, "Gay Witch Hunt" (3.1)
My second favorite from my favorite episode. After finding out that Oscar is gay, Michael and Dwight call Jim to find a gaydar machine (to which Jim suggests trying Brookstone), and then Jim sends Dwight a homemade gaydar, which is really a metal detector. Dwight scans it over Oscar and it goes off around his belt-buckle and Dwight thinks it works. Then he it goes off around his own belt-buckle... and the fear in his eyes is priceless.
