Looking for a forensics piece

I am a member of my school forensics, and need to find a very particular type of literature to perform.

The main problem is that it has to fall into two categories at the same time: Group interpretation and duo interpretation.

Since you most likely have no idea what this means, I will list the criteria below:

-there must be at least to characters
-this cannot be a drama piece (ie: no plays or skits)
-it must already be puplished

What it all basically comes to is part of a book or short story. The most important thing is that it must be funny, entertaining, and easy to understand.

Any ideas?

i don't know about stories, but if you want any funny poems try checking some of shel silverstein's books of poems.
happy hunting-
