This episode is classic.
I love it when Chandler gets stuck in the ATM Vestibule with Jill Goodacre and calls the gang to tell them this news, but he can't be too obvious given that she is right next to him... so he mumbles it down the phone and Joey is the only one who gets what he's saying.... and then mumbles back when he clearly doesn't have to!
The part when Ross gets attacked by the cat while trying to tell Rachel about his feelings for her is brilliant as well, when the camera cuts to inside the appartment and you can see Ross outside on the balcony thrushing around with a cat stuck to his back... brilliant!
Chandler: You know, on second thought, gum would be perfection. [thinking]'Gum would be perfection'? 'Gum would be perfection.' Could have said, 'gum would be nice,' or, 'I'll have a stick,' but no-no-no-no-no. For me, gum is perfection. I loathe myself.
