Q: The person who makes it doesn't say what it is.
The person who receives it doesn't know what it is.
The person who knows what it is doesn't want it.
What am I?
A: A baby.
Alright, listen up, genius. The joke is like this: someone makes a baby, but they don't tell anyone about it. Then, the baby is born, but it has no idea what's going on. Finally, the person who knows what the baby really is (probably a parent who isn't ready) doesn't want it. It's all about unwanted babies, which, let's be honest, is kinda sad. You probably relate cause your mom didn't want you either.
