Dr. Pyckle and Mr. Pride

In a parody of Dr. Jekyll and Mr. Hyde, respected Victorian scientist Dr. Pyckle concocts a powerful potion. After testing it on himself, he transforms into the fiendish Mr. Pride. However, instead of committing evil deeds, Mr. Pride's only goal is to pull elaborate and compulsive practical jokes on the unsuspecting citizens and police of London, causing widespread chaos and confusion.
