repeat after me

There were some buildings. They could walk.

Then there were some vampires. One of the vampires bit the tallest building but his fangs broke off. Then all of his other teeth fell out. The vampire started crying.

The other vampires said, "Why are you crying? Aren't those just your baby teeth?"

The vampire said, "No, those are my grown-up teeth."

And the vampires knew he couldn't be a vampire anymore so they left him.
