WASHINGTON, June 30 (Reuters) - Pfizer Inc. (NYSE:PFE - News) is warning pharmacists that fake Viagra tablets have been sold through at least one retail pharmacy in California and likely a second, U.S. regulators said on Wednesday.
The Food and Drug Administration said it and Pfizer "are analyzing the counterfeit product to determine its true composition and whether it poses any health risks."

Why in the world would anybody want to buy fake Viagra?
