Jennifer Aniston is co-hosting Ellen today, and as part of the festivities, the show put together this mini Friends reunion with Aniston, Matthew Perry, and Courteney Cox. It's pretty cute, if you like your celebrity bits kind of sarcastic and self-deprecating. (And we do!) An actual Friends reunion is a terrible idea, plus these little spots — and the various guest roles on Cougar Town and Go On and Web Therapy, etc. — more than scratch that itch. Also, if there were a Friends reunion, someone would have to acknowledge that Monica and Chandler's twins just turned nine. Nine! Time flies.
