 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 didnt  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.
