Once there was this kid that wanted to shower with his dad, so his dad said yes. Then he asked, "What is that?" and his dad said it's a chow chow train.
The next day, he wanted to shower with his mom, so she said yes. He asked again, "What is that?" and she said it was a tunnel with light.
The same day, he wanted to sleep with them, and they said yes.
In the middle of the night, he woke up and told his mom to turn on the light because the chow chow train is going in.
