Ok so I'm on lunch and don't really have enough time to make a real entry but here are the answers for the quotes:
Thursday: Gilmore Girls - Emily and Lorelai
Friday: Friends - Chandler and Ross
Saturday: Seinfeld - Elaine and Jerry
Sunday: Walk the Line - Joaquin Phoenix and Reese Witherspoon
C1: Is that what I think it is?
C2: What do you think it is?
C1: An orange whirly thing in space
Good luck all!
