Any man worth the hair on his balls knows that the cinnamon challenge is for pussies. A much older and more venerable challenge is the Bengay Challenge. It has been attempted in fraternity houses and college dorms for generations.
The challenge: Take about a tablespoon of Bengay and apply it to your testicles.
Bengay Challenge classic tagline: "Are you a man or have you Bengay?" Put Bengay on your balls and we'll find out!"
