Frank I have a high "ape factor" and only have caplets (whatever) to run through the micrometer (perhaps the width to length problem gave me the headache) but even then a tangent tells me you have won the bar bet. Which relieves me, as I tire of being pistol whipped with a roll of Susan B. Anthony silver dollars by a NOW member for winning. My big money winner in a bar is, "How many teaspoons in a tablespoon?" I may go home alone, but my muffins don't blow door off the oven.
