Photographer Andreas Achmann recently did a Viagra shoot for Vanity Fair's No. 17/2008 issue entitled "Wie Steht's Denn?" which in German translates to "How are things standing now?", used similarly to the way "What's up?" is used in English.
The shoot creatively uses cactus plants to depict a wide array of male genitals of all shapes and sizes.
The plants with the Viagra branding show healthy depictions, while the other ones feature less desirable shapes and sizes.
I think they are just hilarious, especially when you know that Andreas Achmann is a high-caliber photographer with a long VIP client list that includes Levi's, Hermes, Shiseido, Maxim, and Elle.
