Sam Spade - "make your hair stand on end"

In the introduction each week, the Sam Spade radio program would begin: "Guaranteed to make your hair stand on end." Given the fact that Spade's dry, tongue-in-cheek narration often has a humorous tone, and hardly any of the episodes were genuinely scary, the line hardly was an accurate description. I suspect it had much more to do with the sponsor, Wildroot Hair Tonic, than it did with the nature of the program.
