[1] Ross drags the gang, including Tag, up onto the roof to look at the "Bapstein-King" comet, but no one is entirely interested.
Two hours later, Rachel and Tag escape to go watch a movie together; and Phoebe, Chandler and Monica retire to get some sleep.
The two attempt to climb down the fire escape, but discover that the bottom-floor ladder, which is supposed to slide down to the ground, will do no such thing; eventually, Joey serves as the bottom segment of the ladder, and Ross climbs down him so he can shimmy down and drop, but he is too scared.
Chandler then proposes that he and Monica stay up all night talking to each other like when they first started dating, to which she agrees.
When Chandler implies that they can have sex in seven minutes, Monica misunderstands and breaks out the vacuum cleaner and furniture polish to clean the living room.
Eventually they raid the office, where Rachel discovers Tag was right, but works out a subterfuge so that she can sneak them into his desk drawer.
