A doctor was doing his rounds in a hospital when he overhears a conversation between two African nurses.
One says, “It’s spelled ‘whoooom’.”
The other says, “No, I’m sure it’s spelled ‘whooouuum’.”
They carry on like this for a bit, then the doctor goes over to them and says, “I’ll settle this for you, it’s spelled ‘womb’.”
One of the nurses replies, “Look, I doubt you’ve ever seen a hippo, let alone heard one farting underwater’.
