ELI5: Explain Like I'm 5

I'm a teapot

Well, you know what a teapot is, right? It's a special type of pot that you use to make tea. Some teapots are very fancy and pretty with lots of decorations, and some are plain and simple.

Now, imagine that the teapot could talk and it told you "I'm a teapot!" That means it's identifying itself as a teapot. It's like when you say "I'm a little boy/girl" to tell someone that you're a child.

But why is this important? Well, sometimes computers and websites use a special code called HTTP to communicate with each other. And one of the messages that can be sent is called a "status code". And one of those status codes is called "418". And the message that goes along with that status code is "I'm a teapot".

It might seem silly, but this message is actually a joke that some programmers put in as an Easter egg. It's kind of like a secret message that only other programmers would understand.

In a way, it's just a fun way to show that even computers and websites can have a sense of humor. And who knows, maybe one day you'll be a programmer too and you can come up with your own fun Easter eggs!
