"Wait a minute, Doc. Are you telling me you built a time machine..."
Michael J. Fox's Marty McFly asked this immortal question to Christopher Lloyd's Emmett "Doc" Brown in 1985's "Back to the Future."
Some 35 years later, the star duo's reunion for Fox's charity proves that friendship doesn't fade, even if time does fly faster than a speeding DeLorean.
Both Fox, 58, and Lloyd, 81, posted pictures of the pal pow-wow on their respective Instagram accounts after meeting up at the annual poker tournament benefiting the Michael J. Fox Foundation for Parkinson's Research.
The "Family Ties" star launched the foundation in 2000 after publicly announcing in 1991 he was diagnosed with Parkinson's disease.
"Going 88mph for the @michaeljfoxorg Poker Night," Lloyd wrote, referring to the crucial speed lightning that caused his time-traveling DeLorean to move.

Fox posted picture with a similar pose. "All in with @mrchristopherlloyd at @michaeljfoxorg Poker Night!" he wrote.
The dynamic duo have remained lifelong friends after appearing in three "Back to the Future" movies from 1985 to 1990, co-written and directed by Robert Zemeckis.
"He's living his life as best as he can, and that's better than most of us," Lloyd said during London ComicCon in 2017 about Fox. "I just think he's wonderful."
