MTV's Video Music Awards will air live tomorrow night, September 6th, at 8 p.m. ET (7 p.m. CT)—make sure to tune in right here for our rundown of Best & Worst Dressed on the red carpet!—and if there's anything we've learned from the past 20+ years it's to expect the unexpected at the network's biggest show of the year.

So, in honor of the 28th annual MTV Video Music Awards, check out our favorite fashion moments and downright ridiculous non-style-related stunts from the past few decades:

The Britney/Madonna/Christina three-way in 2003:
The ultimate VMA moment of (maybe) all time, the kiss between Britney Spears, Christina Aguilera, and Madonna made us forget all about the amazing "Like A Virgin" homage that happened seconds before.

Kanye West ruining Taylor Swift's acceptance speech in 2009:
Probably one of our all-time favorite fails: Kanye West stormed onto the stage during what was supposed to be Taylor Swift's acceptance speech in 2009. To be fair, Beyonce's "Single Ladies" video was the s***.

Bruno's butt in Eminem's face in 2009:
Technical malfunction or devious plan? In 2009, Bruno, aka comedian Sacha Baron Cohen, bared all—literally—when he descended from the ceiling and his crotch and backside hilariously landed in Eminem's face.

Beyonce announcing her pregnancy in 2011:
Here at StyleBistro HQ, we're pretty sure that Beyonce can do no wrong. But when she unveiled her baby bump at the end of her performance in 2011, there were definite tears of joy. Lots of them.

Beyonce performing "Single Ladies" in 2009.:
There are too many amazing Beyonce moments to count, but her "Single Ladies" performance sealed the deal—she's not only one of the most talented singers around, damn can she rock a leotard.

Lady Gaga's "Paparazzi" performance in 2009.
Lady Gaga is always outlandish, but her "Paparazzi" performance at the 2009 VMAs with the blood and hanging was her first real step towards the theatrics she's known for today.

Britney Spears "I'm a Slave For You" performance in 2001:
There are plenty of Britney Spears moments—VMA and non-VMA—to go around, but one of her most memorable was her "I'm a Slave For You," performance in 2001. Her abs in that green crop-top are almost as deadly as the live snake she's carrying her neck!

Diana Ross jiggling Lil' Kim's pasty in 1999:
First, Lil' Kim wore a bare boob with a pasty to the 1999 VMAs. Second, Diana Ross proceeded to jiggle said boob on stage. That's all.

Whitney Houston and Mariah Carey wearing the same dress in 1998:
Ruh roh! In 1998, two of the music industry's most dynamic divas, Whitney Houston and Mariah Carey, stepped onto the VMA stage to present an award in the same exact dress. Both then proceeded to rip part of the dress off. If blogs were around back then, there would have been a ton of "Who Wore it Better" posts the next day.

Lady Gaga's meat dress in 2010:
After establishing herself as an over-the-top and avant-garde artist in 2009, Gaga hit the VMA stage in 2010 in a meat dress that we can only assume smelled—a lot. We're sure PETA wasn't pleased.

OK Go "Here it Goes Again" treadmill routine 2006:
After releasing their hit music video, OK Go took their treadmills to the stage for a crazily choreographed (and impressive) performance in 2006.

Michael Jackson and Lisa Marie Presley's kiss in 1994:
Everyone had their doubts about Michael Jackson and Lisa Marie Presley, and this awkward kiss at the 1994 VMAs didn't help their case at all.

Diddy and Snoop Dogg's tribute to Biggie Smalls in 2005:
Two of rap's finest paid tribute to the late hip hop legend, Biggie Smalls, at the 2005 VMAs. The heavy instrumentals, beautiful violins, and heartfelt rhymes made the whole thing epic.

R. Kelly's "Trapped in a Closet" performance in 2005:
R. Kelly brought his neverending musical soap opera to life on the 2005 VMA stage. He even revealed his latest chapter (what was it, chapter 56?!) during the show for the first time as a part of his mega drawn-out one man show.

The Wayans Brothers mooning the audience at the 2000 VMAs:
If the Wayans brothers didn't get attention for their matching burgundy suits when they opened the 2000 VMAs (but seriously, it's hard not to notice the hilarious ensembles)—then they definitely caught everyone's eye when Marlon mooned the audience!
