In the second episode of Friends, Chandler makes a funny comment when Rachel can’t remember where she left her ring. He suggests that she was with “Dinah” in the kitchen, but viewers may not understand why he said that. It turns out that “Dinah” is a reference to a popular song that many people know.

The song is called “I’ve Been Working on the Railroad,” and it’s been around for a long time. One of the verses says “Someone’s in the kitchen with Dinah,” and Chandler is using that line to make a joke. He’s teasing Rachel about forgetting where she left her ring by pretending that she was with someone named Dinah in the kitchen.

Even though viewers may not have understood the reference at the time, it’s now a fun fact that Friends fans can enjoy. Chandler’s “Dinah” comment is just one example of the show’s humor and wit, and it’s a reminder of how popular culture can bring people together.
