When Joey (Matt LeBlanc) finds the keys to an expensive Porsche at Central Perk, he thinks it's a good omen -- and as usual, he begins putting the cart before the horse (or in this case, the Porsche) in a ridiculous fashion. In other developments, Monica (Courteney Cox) and Chandler (Matthew Perry) are finagled into babysitting for Phoebe's (Lisa Kudrow) triplets, a night of terror which ends with Chandler swallowing a toy. And Ross (David Schwimmer) and Rachel (Jennifer Aniston) run into a legal snag as they endeavor to annul their quickie Las Vegas marriage. ~ Rovi
