#TBT 'Laguna Beach' Edition: See Stephen, Trey And Dieter In Their Teenage Glory

Check out this old-school gem of the SoCal buddies.

From Blink 182 concerts to local fashion shows, Stephen Colletti, Trey Phillips and Dieter Schmitz were inseparable as they chronicled their senior year adventures on "Laguna Beach." And fortunately for us loyalists of the 2004 series, we just got another taste of the fun-loving dudes in action -- courtesy of the fella who always threw the best house parties and barbecues.

"Over 20 years bouncing around with both these guys, and many more to come!" Trey captioned the grinning and sunny snapshot of the Three Musketeers -- and some pretty sick O.C. scenery. Seems like only yesterday these guys were hanging out with Lauren Conrad and company, contemplating their promposals and saying goodbye to their high school tenure.
