Ah, the nostalgia of "Friends" lives on! It seems that Jennifer Aniston and David Schwimmer decided to pay tribute to their fellow castmate Matthew Perry with a little inside joke. They posted a photo of a text conversation between them, reenacting a classic gag from the show. It's heartwarming to see the bond that still exists between these actors after all these years. I guess some friendships really do stand the test of time, just like Central Perk's lumpy couch.
