I have discovered something even more addictive than reading TVTropes.org entries.
Writing TVTropes.org entries.
So far I have expanded the entries on
Buster Keaton and the short "One Week," created one for his film
Sherlock, Jr., posted queries on three tropes I couldn't find, and am currently working on a page for another Keaton short, "The Haunted House."
So much for doing laundry...
