- Look what I got... a brand-new bill, just like in the violin case!

- Quick! Hide it!

- Now, about that audition...

- Not right now. We've really got to go.

- What? What's the rush?

- Freddy's right. We really got to go.

- Well, we sure enjoyed the puppets. Good-bye.

- Anytime. Anytime. Good-bye.

- Well, why the rush? We didn't get a chance to look for clues.

- Show them the clue, Shaggy.

- Here it is. I found it sticking out of the doorman's desk drawer.

- A brand-new $20 bill.

- And I'll bet you a doughnut it's a phony.

- It sure looks real.

- Let's change it into a blockbuster pizza. Yeah!

- Be serious. My expert opinion on the authenticity of this bill is... it's absolutely genuine.

- You think that 20 was planted to throw us off?

- How come?

- Yeah, like, why?

- To make us think nothing fishy was going on in the theater.

- And then we wouldn't think of going back.

- I get it, but now what do we do?

- We go back.

- Huh? Roh, no.
