Girl: PEEEYOO! What are you putting on those flowers? Frazz: Manure. Girl: What's manure? Frazz: You don't know? Girl: I know what it smells like, but I can't say it here. Frazz: Keep thinking. Maybe there's a different word for it.
From http://historymoment.blogspot.com/2011/03/trumans-manure.html:Harold Truman made a speech at the Washington Garden Club. He praised the ladies for the good “manure” that used to fertilize the flowers. One of them asked Harry’s wife, Bess if she could make him stop using such a vulgar word as “manure”, especially since he was the President of the United States. She replied, “Heavens no. It took me 25 years to get him to say ‘manure.’”
