Six pistol-toting Brazilian men appeared to have more than cash on their minds when they robbed a drug store in Rio de Janeiro. "They specifically demanded that we give them anti-impotence drugs. These drugs and the money was what interested them," Ailton de Souza, the drugstore manager, told Reuters on Tuesday. On Sunday night, the robbers opened the vault with a blow torch and fled with an equivalent of about US$7,000 in cash and checks, as well as more than 100 boxes containing 400 pills worth about US$2,600 - enough for a two-month sex marathon for each of the six robbers.
