In celebration of the upcoming royal wedding, a British brewer has crafted Royal Virility Performance beer. Just three of these stiff brews is equal to taking a Viagra pill. From the article: "Just 40 bottles of the £10 tipple will be produced initially, and will go on sale on April 29 at BrewDog.com. All the proceeds go to the charity Centrepoint, which Wills supports. But buyers will be limited to one bottle each due to the powerful effects."
