Here's one I recall my father's using although if it was original to him or not I know not. In regard to a person with lots to say without much thought behind the words : "He suffers from a constipation of the mind and a diarrhea of the mouth." Anyone else heard that? Or similar? I know I keep asking stupid questions but on the upside I believe you're never too old to learn especially when you are lucky enough to run with erudite company. WOW
