You're sleeping, but suddenly, you hear Kaiser's voice. He's telling a joke.

"Two fish are in a tank,One of them says,you drive, and I'll man the guns!'"

Even though you're still tired, you can't help but smile at his joke. Kaiser's silliness is part of what makes him so special to you. In your half-asleep state, all you can do is chuckle at his wacky humor.
