this was actually a nice ending to the show, it was very conclusive and i liked it a lot. some parts i thought were funny:
~how nobody but the doctor knew Erica was having twins
~how joey asks for a muffin when Ross and Phoebe leave to go see Rachel before she boards the plane
~when Rachel boards the plane and says her seat number is the same as her bra size
~when the twins are born and then Mike and Phoebe start talking about babies
~and when the Foosball table had to be broken apart to save chick jr. and duck jr. i also really liked the end, when they all give up their keys and all that stuff, it was very sweet.
