After Chandler sneaks into town without telling anyone, Joey is convinced that Monica is having an affair with another man. So then, he calls Chandler, who is really across the hall, and tells him everything! Chandler and Monica make up a plan to outwit Joey, but he ends up finding out.
At the bar, Rachel gives her phone number to a man and after, has second thoughts because he might call the apartment and Ross might answer! So then, Phoebe sends Mike over to stall any phone calls, which creeps Ross out, and the two boys end up sitting on the couch in an awkward silence.
But in the end, the guy from the bar ends up calling and leaves a message, but Ross doesn't tell Rachel about it...
This episode is a tearjerker. It was so funny and at the same time, dramatic (on Rachel and Ross' behalf).
