Have a Heart (1928)

In this lively late silent two-reeler, blundering blowhard Jimmy is "always looking for work; someday he'll find it, then he'll have to quit." But meanwhile he applies for a job at a newspaper whose editor really, really wants to solve the mystery of the "haunted" Klutz Mansion. So our hero and the boss' daughter go to investigate a spooky abode that may not have actual ghosts but does have an actual mad scientist in residence.
