It's been 30 years since Back to the Future taught us that traveling back in time to hook up your parents is, like, totally weird... and awesome if you get to do it while driving 88 mph in a souped-up DeLorean.
In honor of the sci-fi classic turning 30 (or 60 if you count from 1955, the year Marty McFly travels to), here are 10 ways to completely nerd out on all things Back to the Future.
1. Snag your own Back to the Future DeLorean
Step 1: Buy a DeLorean
Step 2: Have these folks transform your DeLorean into one of the Back to the Future vehicles.
Step 3: Skip steps one and two and just rent a Back to the Future DeLorean instead. You know you wanna cruise around your neighborhood in one of these bad boys...
2. Grab this Marty McFly costumed T-shirt and wear it like a boss. Own your fandom, people!
3. Watch a really cool video on how they created the film's intricate (and awesome) opening scene.

7. And speaking of Legos, did you know there's a Back to the Future Lego set? And did you know that it's AWESOME?!
8. If you thought Michael J. Fox and Christopher Lloyd stopped playing Marty and Doc after 1990's Back to the Future III, you'd be wrong. Lloyd in particular has continued to play Doc in numerous TV commercials and viral videos over the years, with the latest being this ad for Lego Dimensions.
And who can forget his cameo as Back to the Future III's Doc in A Million Ways to Die in the West.
Meanwhile, the closest Fox came to reprising his role as Marty McFly probably came back in 2011 when he performed a version of "Johnny B. Goode" live onstage.
And here's the part in the movie he's re-creating in the video above.
9. See proof that Back to the Future's iconic score by Alan Silvestri works for any movie, really.
