Mr. McDougal, played by Frank Ferguson, is a character in the film Abbott and Costello Meet Frankenstein.
Mr. McDougal arrives at a shipping company to check in on his crates. He wants them to be personally delivered to his business, "McDougal's House Of Horrors".
Inside the crates are Count Dracula's coffin and Frankenstein's Monster. When Wilbur Grey discovers that the Dracula is actually in his coffin, Chick Young doesn't believe him. Dracula mesmerizes Wilbur and revives the Monster. The two of them leave while Wilbur cannot remember anything.
When Mr. McDougal shows up to his museum, he is outraged that his exhibits are missing and accuses Wilbur and Chick of stealing them. After Wilbur and Chick are bailed out of jail, it is revealed that Mr. McDougal hired an insurance investigator to follow Wilbur around.
