BARBRA STREISAND is sick of advertisments for anti-impotence drugs, deeming them "morally questionnable". The singer and actress claims Hollywood films hardly ever shape our moral attitudes, unlike commercials for CIALIS, which improves a man's ability to function for up to 36 hours. She moans, "I resent this thing about Hollywood and moral values. What movies are out now that have questionable moral values? "You know what I think has questionable moral values? The Cialis commercials."
