The cast of “Friends” sat down with “People” magazine to talk about their upcoming reunion special…and there was something very off about Matthew Perry.

He was hunched forward most of the time, and when he spoke, he seemed lethargic and a little slurry.  He also had a bit of a vacant stare at some points.

He did get a joke in, though, when he said that the chemistry between the guys was very sexual.

Obviously, we don’t know if this had anything to do with it, but Matt’s had his issues with substance abuse over the years.  There’s no word yet from his people.
