Taylor Swift has dragged out many, many, many special guests during her 1989 World Tour, but few, if any have inspired this much 1990s nostalgia.
Introducing her as Phoebe Buffey, Taylor Swift brought Lisa Kudrow up in front of the screaming stadium for a quiet and intimate rendition of Kudrow's song Smelly Cat from this little show you might have heard of called Friends.
Heres a wider, much stabler video:
If you're unfamiliar with Smelly Cat because maybe you were born in the 90s and too young to bask in the ultra-caucasian glow of Friends, you can watch the original here:
And we will now open bets as to who will join Swift on stage yet. Norm from Cheers? Garfield the cat? George W. Bush's twin daughters? The Count from Sesame Street? That crazy astronaut who wore a diaper to confront the rival for her love?
Who knows!
