Bob Hope's Handkerchief

Origin
Bob Hope (born Leslie Townes Hope; May 29, 1903 – July 27, 2003), was an English-American comedian, vaudevillian, actor, singer, dancer, author, and athlete. With a career that spanned over 60 years, Hope starred in over 70 films and short movies. In many of his comedian shows, he had a handkerchief in his pocket which became imbued with his ability to make anything he said funny.

Effects
The Handkerchief causes anyone in possession of it to be funny in everything they say, even if they are not trying. However, the handkerchief may cause the user to commit extramarital affairs, although the downside does not always show up.

Collection
Agent Arthur Neilson went to Hope's house after his death in 2003 to look for any artifacts in his possession. The only artifact found was Violin which caused people to laugh at whoever played it. Artie asked if anyone had been there before him, and found out that several objects which appeared to make people laugh were taken; the Handkerchief was among these objects. Artie was unable to track down the people and the artifacts and periodically searches for any unusually funny comedians. As of yet, there has not been a ping on this artifact.
