The Wall Street Mystery

Dr. Crabtree:
I once dropped a nickel in a phone box and got back twenty dimes. Isn't that Wall Street?

Insp. Carr:
What are you up to?

Dr. Crabtree:
Up to my neck in clues.

Dr. Crabtree:
Wall Street? Well, there's nothing mysterious about a killing on Wall street. I made one myself.

Insp. Carr:
What's your name?

Abraham Washington:
[Timidly] Andy Amos Lindbergh.

Insp. Carr:
[Gruffly] Is that your real name?

Abraham Washington:
[Nervously] Yessuh! I was named Abraham Washington, but I done baptized myself for something more famous.
