Joey and Rachel have an adorable relationship on 'Friends'. The two are incredibly supportive of each other and are always having a great time together, even during their brief four-​episode-long fling. 

But off-screen, Matt LeBlanc and Jennifer Aniston are just as cute. In ​one scene during Season 6, Rachel is staying at Joey's and having fun throwing wet paper towels at the cabinet. She shouts, "I love it at Joey's!" And Joey actually helps her out with the line.

Though there have been plenty of other ​goofs during the show, this one is so cute. It really showcases how much the cast works together, and perhaps Jennifer had been having trouble with the line.

We've seen, through many bloopers, the cast helping each other out, so perhaps this was one instance that made it to the screen.
