Television's finest groups of pals all have their go-to spot -- for the Friends gang, it was Central Perk; the 90210 crew could be found at The Peach Pit. And the cast of The Hills more often than not was spending their evenings (with bottle service) at Les Deux -- never forget the dimly lit club with the paisley wallpaper.

In honor of the iconic MTV series turning 10 years old this week, we're toasting the former Hollywood club (yes, it sadly closed back in 2010) and remembering the most unforgettable evenings that unfolded in the VIP section at the bar. From Jen Bunney's birthday to Lauren declaring those iconic five words ("you know what you did," obviously), LD was the backdrop for some classic small-screen moments. Raise a glass of bubbles, take a peek at the videos below and be sure to stay with MTV News for more updates on the Lauren Conrad special The Hills: That Was Then, This is Now.

Heidi's Big 2-0

The Colorado native certainly relished being the guest of honor -- heck, she carried her cake around and posed with the elaborate dessert. But the shindig wasn't without awkwardness -- specifically, Heidi giving Audrina the cold shoulder.

The Infamous Birthday

The Laguna Beach pals would never be the same after this celebration because of the guest of honor's supposed hookup with Brody Jenner.

"You Know What You Did"

Enough said.

Awkward Date

Poor Lauren wasn't really feeling Derek (we've all been there), but at least she was at a comfortable location.

Obvious Lauren/Brody Tension

Simply put, the pals hit a rough patch after the Teen Vogue intern returned from Paris. And SCENE.
