What's wrong with Matthew Perry?

We will forever LOVE the cast of "Friends" and the reunion special coming to HBO Max has us all dancing. We see Jen doing her Aveeno commercials and Matt on "Man with a Plan", but we miss them at Central Perk doing all the things that make their characters, well, characters. Do they hang out a lot? How often do they talk and keep in touch? Do they have their own "Friends" reunions? Did they take anything from the set when the show ended? The questions are endless! But through the whole interview, Matthew Perry just seems "off". Vacant stare, slurry words, kinda scary. Watch the interview and judge for yourself.
