I think this is one of the very first time that we hear someone of Friends insulting without censorship. That's why I define the first two minutes of this episode as the greatest comedy performance of Courtney Cox (Arquette) on Friends.
I just couldn't stop watching over and over Monica screaming "Son of a..." to herself. :D
The rest of the female cast goes along with her, and the boys (on their own stuff) really crank you up.
This is one of those episodes that become impossible to forget, although it is not among the best ones. Just the stuff that made Friends a classic, and really worth the twenty minutes sitting.
