Season 7: Episode 157: The One With All The Cheesecakes
Phoebe and Joey feud over what constitutes a proper excuse to flake out on their weekly dinner plans -- and it's driving her batty, especially since her old flame David (guest star Hank Azaria, "The Simpsons") has returned from Russia for a romantic one-night date. Elsewhere, a gluttonous Rachel and Chandler disgrace themselves when they repeatedly swipe deliveries of an exquisitely tasty cheesecake from their neighbor's doorstep while Ross reluctantly takes a seething Monica along to their cousin's wedding just so she can berate the bride for not inviting her as well.
