Who drew a mustache on a photo of Wendy Pepper's daughter? The mystery was never solved, but it didn't do much to ease tensions brewing between outsider Wendy Pepper and, well, every other designer on the show.

After landing in the bottom three on the "Clothes Off Your Back" challenge, Andrae pretty much lost it on the runway, openly weeping through a monologue about... well, we don't really know what it was about, only that it was loooooong and kinda embarrassing.

Nina Garcia didn't get Santino's vision for a lingerie line ("It's aesthetically not pleasing," she said of his Heidi-meets-forest-creatures getups), he snapped back to the fearsome magazine editor, "Well, I'm SORRY, Nina.... I think it [lingerie] is supposed to come off, that's what I think!" Okay, then.

All together now: "What happened to Andrae?" Santino had his fellow designers (and us) cracking up, perfecting his Tim Gunn-speak by concocting a story about the dating adventures of the Parsons mentor and fellow contestant Andrae Gonzalo. Brilliant for so many reasons, but mainly because Santino made Red Lobster cool again.

Keith Michael, an early front-runner in season 3, was disqualified from the competition after pattern books were discovered in his room. Remember that stern talking-to he got from Tim Gunn? Chills.

The "Everyday Woman" challenge, in which the designers made clothes for female relatives of their competitors, was already awkward enough. But nothing was more awkward than the interactions between Jeffrey and his client, Angela's mom, whom he dressed in an awful blue tent and then berated on the runway.

Such mixed emotions: On one hand, we were devastated to see Jack leave due to medical reasons... but on the other, we were excited to see Chris March get back in the competition. Quite the pickle!

When teenagers visited the designers of Project Runway to consult on prom dresses, things got a little bit high school. Watching Christian and his client, Maddie, bicker like they were in the cafeteria was no exception to this. It was like a scene from Mean Girls when Maddie said, "Admit it. You love me!"

Sarah Jessica Parker?!!? On Project Runway?!?! Dreams came true the day that the designers teamed up to create a trendy look for SJP's line Bitten.

Sweet P was aghast when Elisa spat on their fabric. But as far as the quirky Elisa was concerned, she was merely killing two birds with one stone: measuring the garment AND infusing her soul into it. Ooooookay.

In the first season finale, the Pepper finally got what was coming to her when Jay McCarroll voiced what was on all of the designers' minds. "Everyone hates you!" he told Wendy. Slightly immature? Yes. Harsh? Totally. Honest? Very.

Which designer uttered the immortal line: "Where the HELL is my chiffon?" To this day, the voice behind the line is still an unsolved Runway mystery. Andrae says it was Daniel, Daniel says it was Andrae, and Tim Gunn thinks it was Daniel impersonating Andrae. We'll let you be the judge.

During a soiree with socialite Nicky Hilton, the designers decided to have a runway-style walk-off. Santino nailed it, Marla was awkward, and Lupe busted out a forbidden dance move: the worm. The winner? Nick Verreos, who owned the "runway" and did the best televised twirl we've ever seen.

Turmoil, tension, tears, tantrums... it's expected whenever the designers are grouped into teams. Creative visions tend to clash, and the outcome is worse than pairing stripes with polka dots. Such was the case for Season 2's Kara Janx and Zulema Griffin: When Kara turned on the tears, partner Zulema laid down the law. If you're gonna cry in the workroom, then cry, she told Kara. "But cry and CUT."

Winner of the week Zulema turned up the heat when she held her own impromptu challenge for the models, summed up perfectly by Daniel V. "It's a motherfucking walk-off!" Andrae and Nick's shocked reactions are what reality TV is all about.

During Fashion Week, there is usually a flurry of last-minute fittings and finishing touches. Then there was Jeffrey Sebelia, who sat around looking bored. This didn't fly with Laura Bennett, who told Tim that Jeffrey may have been a cheater, guilty of outsourcing sewing work. Viewers had to wait a whole week for the final verdict (not guilty), in what was Runway's most dramatic cliffhanger.

During the WWE challenge, viewers learned the answer to a question we never thought to ask: What would Christian's diva wrestling name be? Ferosha Coutura, obvi. His finishing move? Blinding bitches with hairspray.

Between Nina's glares of disapproval and Michael's sneers of disgust, it's sometimes hard to tell if the judges are actually having fun. In a rare moment while sitting around the WWE ring, the poker-faced judges finally broke, thanks to one model's pelvic thrust that had the judges falling over with laughter.

In the moments before the fourth season winner of Runway was announced, the normally peppy Christian Siriano looked gravely serious. But the Fan Favorite's cocky confidence returned shortly after securing the win. "People need to see more of the fierceness," he told the judges. Not only did Christian win a load of prizes, he also won the approval of guest judge and style icon Victoria Beckham. He got her to smile (no small feat) and told her, "We'll be in touch."

The day-glo, fake-baked Blayne got his ghetto on to teach his homeboy Tim Gunn some of the latest slang on the streetz. After his lesson, the astute, well-spoken Tim told his designer dawgs, "Holla at yo' boy!" Holler, Tim!
