Porky is a police officer, who is in a poice car that is named 6 7/8. He gets a call from his chief to go investigate goings-on at a haunted house. The house is haunted to the core, and the fun loving ghost plays a series of pranks on the unsuspecting pig. As Porky knocks on the door to enter the haunted house, the ghost does a lady voice "Come in." Porky enters, already frightened. He enters again, the ghost places Frogs into a pair of shoes to look like a person walking, as Porky doesn't notice, the laces of the shoes get stuck to a coat hanger pole then rips of a cutain to make it look like a person with a cloak on. It immediately scares him and then the ghost scares him. Porky runs upstairs and lands in the ghost's arms with realizing, until that famous line comes as the ghost says it very goopy. "What the matter baby?". Porky is finally scared out of the house, but he has the last laugh when his back-firing car leaves the ghost in blackface (and the ghost doing a Rochester imitation).
This cartoon was shown as a colorized version (either redrawn from the 1960s or an early-1990s computer-colorized version) on syndicated airings on local channels, on Cartoon Network shows outside of The Bob Clampett Show and Late Night Black and White (i.e., The Acme Hour, The Looney Tunes Show, and Bugs and Daffy), the Merrie Melodies Show when it aired on the Fox network, and on Nickelodeon so the ghost would be opaque and yellow. The actual editing of the ending (where the ghost, after getting exhaust smoke blown on him, is left in blackface commenting "My, oh my! Tattletale Gray!") has been done in different ways:
The syndicated showings showed the actual ending, but had the ghost in purple face so the blackface joke would be less offensive.
On Nickelodeon, the cartoon ended via fake iris-out after the exhaust on Porky's car blew in the ghost's face.
On Fox's Merrie Melodies show, the cartoon ended via fake fade-out after Porky drove his car past the ghost.
On Cartoon Network (save the versions shown on Late Night Black & White and The Bob Clampett Show), the cartoon ended with a black-out as Porky's car blows exhaust in the ghost's face.
