The film begins animated versions of Abbott & Costello on a scaffold painting their names on a wall. (The bucket is labeled "BLOOD")Then there is the sound of a car screeching to a stop, and machine gun fire. "Meet the Killer" is written in bullet holes. "Costello" yells "Yoohoo! You didn't dot the "I"!" Then a dagger flies in and "Dots the 'I'", while the bucket of "Blood" is spilled. Then the frame drops, following the "Blood" as it spells out "Boris Karloff", and then the rest of the credits.
