Favourite Friends season-finale cliffhanger?

So, Friends usually always left us with a cliffhanger at the end of the season, leaving us waiting for the next one to start. Which one was your favourite?

Season 1 - The one where Rachel finds out.
Rachel finds out Ross has a crush on her, so goes to meet him at the airport, only to find him coming home with a new girl in his arms.

Season 2 - The one with Barry and Mindys wedding
Chandler discovers his true love he met online is Janice.

Season 3 - The one at the beach
Rachel tells Ross she still loves him, so now he must decide between Rachel and Bonnie. He opens a door, but who's door?

Season 4 - The one with Ross' wedding
"I Ross"
"I Ross"
"Take thee Emily"
"Take thee Rachel"

Plus, Chandler and Monica hook up.

Season 5 - The one in Vegas
Monica and Chandler decide to get married, but they are interrupted as a drunk Ross and Rachel burst out as newlyweds.

Season 6 - The one with the proposal
No real cliffhanger - Monica and Chandler get engaged.

Season 7 - The one with Monica and Chandlers wedding
Monica and Chandler get married, and it appears that Monica is pregnant. Nope, the last shot hints that it is actually Rachel who is pregnant.

Season 8 - The one where Rachel has a baby
Rachel gives birth to Emma, and Ross plans to propose. Joey, finding the ring, turns round, which Rachel mistakes for a proposal - and says 'okay'.

Season 9 - The one in Barbados
Joey and Charlie break up, leaving them both single. Rachel declares her crush on Joey, but Joey refrains, until he sees Ross and Charlie together, then decides to go and find Rachel for a kiss.

Season 10 - The one with Princess Consuela (mini cliff hanger)
Rachel reveals she's accepted a new job - In Paris.

I know this wasn't the true season finale, but I didn't think the last one would count, and this episode was followed by a 2 month hiatus.
