This is one of my favorite episodes of the series, not only because I lived in London for a while and it was fun to go to the same places they went, but because this episode cracks me up... joey is at his best performance, pissing Chandler off all the time, and saying the most ultrageously funny thigs!!!
Monica is great too helping Ross with Emily and all.... But the best part for me is Monica and Chandler in the hotel room, when they see each other naked for the first time!!! It is the funnies scene they did toghether!!!! Great episode!!!
