Mrs. Mabel Van Moo is an insane, overweight, middle-aged character that belongs to the theater of the grotesque, where only caricatures are admissible.

The scenes of the situational comedy Spiffies and Loonies. in which she intervenes have been collected to constitute this booklet for actors and actresses who wish to impersonate that outrageous individual for its own sake. Mr. Van Moo is driven by her secret desire to become the lover of a handsome young man, Brad, her passion being disguised as a sort of motherly protection. At a time she even plans to marry him, although Brad is deeply in love with a peach of a girl named Dolly, and soon becomes her husband. She stalks him in various indirect ways to the extent that everybody worries about the consequences. In order to get rid of her family duties, she tries to make her son, Mickey, marry Twiggy, both being against the match.
