The season 5 finale, The one in Vegas was a classic.
All storylines were hilarious.
Ross and Rachel drinking too many 'beers and alcohol' was the cause of some laugh out loud moments in this episode. And the wedding at the end - biggest. shock. ever.
Phoebe and Joey's side storylines were also memorable. We giggled as Joey tried to convince his 'hand twin' to start a show, and Phoebe VS The Lurker begins. And plus, she introduces us to Regina Phalange!
Chandler and Monica had a good plot too - Chandler gets angry, they make up, then decide to get married. Touching..... :)
A fabulous episode.
