Watch As Jennifer Aniston Scares The Heck Out Of People On The 'Friends' Set

Jennifer Aniston, who was guest-hosting for Ellen on The Ellen Show (who was out at the DMV getting her license renewed: seriously!), had the opportunity to crack up her in-studio audience with a hilarious video.  Not far from the set of The Ellen Show is the classic (and preserved) set from Friends (which Aniston played on as Rachel from 1994-2004).  Jennifer Aniston decided to have some fun with various tourists checking out Central Perk.  Have a laugh with the video below!
