This is a very good episode. I love the part about Emma only laughing to "Baby got back". Ross and Rachel tried a lot of other things to make her laugh but it's the only thing that works. It was hilarious when Rachel and Ross are singing it together and everybody else walks in.
A classic joey moment was when he and Chandler find a tape with the word Monica on it, and he figures out it's of her and Richard having sex. Chandler gets very insecure about this.
I also loved the part about Phoebe trying to impress Mike's parents. When this doesn't work, Mike tells his parents that he doesn't care whether or not they like her, because he loves her. I thought that was very sweet!
Not the best "Friends" episode ever, but a very good one!
