 PLOT: Chandler says he can sometimes hear Joey screaming at him late  at night like he did at the beach. Joey says that he just does that  to freak Chandler out. However, Phoebe, Ross, and Rachel are all in  the same clothes as they were at the beach indicating that it is  still the same day. Therefore, Joey would not have been able to do  the shouting late at night as they have not slept yet and certainly  could not have been a few times as was implied.
