It's true, Chandler's habit is aweful and it only leads him to trouble anyway. :S
And cups and ice is amazing! But you know, it may seem like a simple idea, but it's not that easy to make all those ornaments in each cup for the little birthday hats for example. She probably spent a lot of time to arrange all that.
I don't like the fact that they forgot Chandler's birthday. :( I mean, I don't mind them forgeting these things once in a while, but does it always have to be Chandler?
Oh, and I think it was so unfair of Kim and that other girl from Rachel's office to stay outside talking about work. It's so disrespectful AND unprofessional.
