Every Friends Joke

Rachel and Ross are at Barry (former Rachel's husband-to-be) and Mindy's wedding. Rachel is a bridesmaid of Mindy today. She has just walked down the isle with her skirt caught in her panties. Rachel: This is so humiliating. The only thing that tops it is when I was in eight grade and I had to sing the "Copacabana" to the entire school. Does she imply that "Copacabana" is a bad or not sophisticated enough song?

Chandler is having an Internet-based relationship with some woman he has never met in person. Phoebe is reading over his shoulder: - What does she mean by HH? Chandler shyly: - It means we are holding hands. Phoebe surprised and slightly mocking: - Are you the cutest? Chandler accepts laughing: - I'm afraid I might just be. Even though all the words look familiar in "Are you the cutest?", the way Chandler respond leaves me guessing that there is a cultural background to it. And this is where I get lost. Can you help, oh, Universe of Friends Fans?
