Mini-'Friends' Reunion Alert! Check Out Their Hilarious 'Ellen' Segment [Video]

Jennifer Aniston asks Matthew Perry for advice on co-hosting a daytime talk show.

"I'll be there for you"? Maybe not at eight o'clock in the morning!

Jennifer Aniston is co-hosting Wednesday's episode of "The Ellen DeGeneres Show," and in this video segment, she hits up her "Friends" co-star, Matthew Perry, for advice. But she shows up at his house a little too early for his taste.

"Some advice?" a bleary-eyed Perry asks. "Well, maybe you shouldn't show up at somebody's house at 8 o'clock in the morning and you should call first!"

A confused Aniston recalls that they used to pop over to each other's apartments all the time. "We're friends!" she says.

"No, that was a TV show," Perry reminds her.

The "We're the Millers" actress doesn't help her cause when she pleads, "Give me something to go on."

"Don't say 'Go On,'" winces Perry, whose NBC comedy of that name was recently canceled.

Their banter then turns into a mini-"Friends" reunion when out pops Courteney Cox! The two women stare wide-eyed at each other. Apparently, Perry's been having his own reunions without Aniston!

And you won't believe who else tries to sneak out of the house. Watch the clip:

Aniston, Cox, and Perry have done their "Friends" some favors since their hit show went off the air. Aniston appeared on Cox's "Cougar Town," while Cox reunited with her TV husband on an episode of "Go On" this season.
