Hank Azaria returns in the role of David, the nerdy but good-hearted scientist with whom Phoebe (Lisa Kudrow) briefly fell in love way back in Friends' first season. Upon finding out that David has come back to New York -- albeit only for one day -- Phoebe is determined to have a passionate reunion. Only one problem, however: Phoebe is currently supposed to have dinner with Joey (Matt LeBlanc). Elsewhere, Ross (David Schwimmer) must play peacemaker when Monica (Courteney Cox) is upset over not being invited to a relative's wedding. And in keeping with the title of the episode, Rachel (Jennifer Aniston) and Chandler (Matthew Perry) have trouble resisting temptation when several cheesecakes are delivered to the apartment by accident. ~ Rovi
