Answer 1

A crawfish stuck in the esophagus. The patient was known to have an esophageal stricture and had to chew the food real well before swallowing it. He was invited to a crawfish party and forgot to wear his dentures. He swallowed the crawfish and it got stuck and had to be removed under general anesthesia the same night.
