Friends Season 8 Episode 6 : The One With The Halloween Party

Monica and Chandler are throwing a Halloween Party. At the party Phoebe runs into her sister's fiance, Eric (Sean Penn), and finds herself attracted to him. Ross and Chandler arm wrestle. Rachel asks if she can be the person who hands out candy to the trick-or-treaters, as she says 'ever since I got pregnant, I have had the strongest maternal instincts', only to find out she isn't as maternal as she thought.
