Query: Thoughts on a Great Man by a Pathetic Loser

Oh, for gosh sakes. Arthur Marx is a complete loser who managed to squeak out a living as a comedy writer only by working his father's connections. Groucho thought Arthur was a lousy comedy writer, and this book proves he's a lousy human being, as well. Hope was one of Arthur Marx's employers, and it was Hope that turned his father's career around by insisting that he work off the script when he invited Groucho to come on the air with him. Little did he imagine at the time that the thanks he would get for his benevolence to Groucho (a benevolence he displayed throughout his career) would be a knife in the back from his pathetic lowlife son. The book is a collection of snide, filthy, innuendos from unnamed sources, former employees, and the sort of enemies that competent, hard-working, brilliant individuals like Hope always make within their own industries.
