Season 5 of Friends was where we really got to see the relationship between Chandler and Monica blossom, and I can’t think of one of a better moments than “The One With All The Thanksgivings.”
This causes Chandler to laugh and inadvertently tell her that he loves her – a moment he quickly and nervously denies, but it was a moment that defines their relationship.
Monica goes to beg for his forgiveness and puts a turkey on her head to try and cheer him up, doing a funny little dance with props as well.
When everyone is going over what their worst Thanksgiving memory was, Rachel accidentally reveals Monica’s, saying that it was the Thanksgiving that Monica accidentally cut off Chandler’s toe because she had been trying to act alluring toward him after she slimmed down, and the plan got botched.
