Frank: Good to see you, Luan. How's my number one customer doing?

Luan: Great, Frank. This is my sister Leni. She wants to become a prankster, too.

Frank: Well, pleasure to meet you, Leni. [He shakes Leni’s hand, shocking her.] That's your first lesson, little lady, the granddaddy of all pranks. The joy buzzer.

Leni: I don’t get it.

Frank: You don't have to get it. The prank is for the enjoyment of the prankster.

Luan: You see, Leni, Frank here is the master. I learned a few of the things I know about pranks from him. [They walk to the counter] Okay, Frank, let's see what you've got.

Frank: Well, this came in just this morning. [shows package of gum] Have some gum. [Leni takes a stick of gum and chews it. Off-screen she screams as her head explodes] Ha! Exploding chewing gum. Only $9.95

Leni: [Her head is reduced to a skull] I don’t get it.
