12 Small Details You Only Notice Rewatching Friends
6. Ross & Monica's Parents Wear The Same Clothes As Their Anniversary Picture
Season eight's "The One In Massapequa" revolves around the 35th wedding anniversary of Ross and Monica's parents, and during one brief moment where the two are stood next to their own commemorative anniversary picture, you can see that, for some reason, they're wearing exactly the same clothing.
The sensible answer is that the prop department forgot to get a picture of the pair before shooting the scene and so quickly snapped a photo while on set, but there are those who would prefer to believe it was a troll on Jack's (Elliott Gould) part.
Still, you do have to question the thought process of the prop department here, because what's more distracting - having no picture at all, or one with the couple in the same damn clothes? Either way, it's hilarious.
