There was a Pretty Lady from Hamm

NOTE: Most of the limericks that I write come from a personal experience or something that I've read in the news.  This one is from two places.
 I am reading the book THE ONE AND ONLY IVAN, and I read this news item:

There was a Pretty Lady from Hamm

Who had for a pet an ancient clam,

But one day a gorilla left its domain

And took away her clam to obtain some fame.

The Pretty Lady from Hamm

Was very sad without her clam.
