Monica is sick and she got a break from work because of that. But the problem is that she doesn't admits that she is sick, and tries to make a lot of different stuff without much success. (The scene where she tries to seduce Chandler is so funny!)
Jill,Rachel's younger sister, comes to visit her. Jill is angry and desperate that her father took all her money and told her to learn the value of the money with Rachel,'' the only daughter who he is proud of ''. Rachel stays happy to know that her father is proud of her and tries to make Jill more independent, using the same techniques she used when she was also wanting to be independent.
Later, Jill and Ross ''have a thing'' going on, and Rachel stays worried that they can get involved.
Ps: Monica sick is absolutely hilarious!
Ps2: I LOOOOVE Phoebe's cloth in this episode!
