Pfizer has a new customer for Viagra— one considerably cuter than Bob Dole. Chinese zookeepers reportedly plan to treat pandas with the anti-impotence pill to improve their chances of reproducing. Male pandas can sustain an erection for only 30 seconds at a time. Viagra is expected to improve their sexual endurance and increase their chances of impregnating their mates. A Pfizer spokesperson responded skeptically. "Viagra's not an aphrodisiac," says Beth Coldwell. "It's only licensed for the treatment of male erectile dysfunction, so it shouldn't be used by any man, woman, or animal who doesn't suffer from that condition."
