The One Where the Monkey Gets Away - S1-E19
Corrected entry: In TOW Rachel loses the monkey, she calls animal control. Ross comes home and is shouting at her when the woman comes. Rachel asks who it is, but never actually buzzes her in, yet somehow she gets in.
Correction: Good timing explains this one. If anyone was coming out, or a resident with a key was going in they could simply hold the door for her.
Correction: It is impossible to know how many apartments are on each level. It is likely that Monica and Phoebe are searching on the third floor at that very moment, meaning they could be on a floor lower than theirs.
