Two fans posing with coffee drinks were surprised then Aniston came around the couch with a coffee pot and asked, "Hi, can I get you a little latte?"
Another duo was startled when Aniston jumped over the back of the couch and yelled, "Espresso!"
“I know, it’s the cruelest thing in the world,” Aniston said to the fans.
And, Aniston feigned mock anger and made a face when two tourists said their favorite character was Joey Tribbiani.
“Joey? Joey? It’s OK, I love Joey too,” she said.
Aniston invited her new friends to watch her as she played substitute host for DeGeneres, E! Online reported.
“Now that you guys are here, you get to watch your third favorite ‘Friend,’” she said.
