Jimmy Kimmel, taking a page from the Jimmy Fallon playbook, took the opportunity of having Jennifer Aniston on "Jimmy Kimmel Live" to act out a bit of "Friends" fan fiction that he had written. Aniston is not exactly game, but plays along, which is good since it turns out Kimmel also got Courteney Cox and Lisa Kudrow to appear as their characters as well. Kimmel plays Ross, mainly because the script is about how great of a lover Ross is.
Kimmel even perfectly recreated the "Friends" kitchen on his stage, right down to the funky looking refrigerator. And if you're wondering what happened to Joey and Chandler, they couldn't make it because of that unfortunate monkey rabies incident with Marcel.
Can't really blame Aniston for rejecting that wig, though.
