Here is your reading assignment, a true story:
Memoirs of a Sword Swallower by Daniel P. Mannix
Might be a little hard to find, but it is great!
After graduating from college (in the 1930s?) Mr. Mannix decides to write the "great American novel" but has no life experience so joins a traveling side-show as a worker, helping to put up and take down the tent. We get introduced to all the freaks including the human pin-cushion, the ostrich, the fat-lady, etc. He works his way up to be a sword swallower! And we get a glimpse of a way of life and of a time that is now mostly gone.
This is an absolutely fascinating and wonderful story.
