Friends is unarguably one of the best shows ever created. Taking you through the lives of six friends living in New York, Friends teaches you so many things, even if you don't notice it. Whether humorous or serious, here are 10 things you can learn by watching the hit show Friends:

1. New Holiday Mascots

Season 7: Episode 10 "The One With The Holiday Armadillo". Ross wants to teach his son, Ben, about the traditions of Hanukkah, but all Ben can think about is Christmas. When Ross finally gives up on Hanukah, he goes to rent a Santa Claus costume, but... well... that's not quite what he came home with.

2. All 50 States

Season 7: Episode 8 "The One Where Chandler Doesn't Like Dogs". It's Thanksgiving at Chandler and Monica's, and Chandler presents the game where you have six minutes to name all 50 states... It's a lot harder than it sounds.

3. Grammar lessons

Season 4: Episode 1 "The One With The Jellyfish". The gang is just getting back from the beach, and Ross and Rachel had just gotten back together after a separation. Rachel has some requirements that Ross must agree to before they can be back together. She writes him an 18 page letter (FRONT AND BACK) to tell him just what he has to do. Ross isn't particularly happy with what she has to say... or her lack of grammar..

4. True Love

True love's comparison to lobsters occurs a few times in the Friends series, but it is introduced by Phoebe in Season 2: Episode 14 "The One With The Prom Video". She says that once a lobster finds one mate, they stay together for the entirety of their lives.

5. What happens when you take somebody's underwear

Season 3: Episode 2 "The One Where No One's Ready". Fighting over a seat with Chandler, Joey leaves and takes the cushions of the chair with him. Chandler, in turn, takes Joey's underwear. To get back at him for that, Joey does the "opposite" and wears everything that Chandler owns.

Ross swears he was on a break with Rachel when he slept with the woman from the copy place, but Rachel sees it differently. In SEVERAL different episodes, Ross tries to convince Rachel that they were. Moral of the story... make sure you were on a break.

7. To say the right name at the altar

Season 4: Episode 24 "The One With Ross's Wedding: Part 2". Ross is getting married to Emily in London... Great! Except, it's not so great when he says Rachel's name instead of Emily's at the altar.
