Browsing through this is akin to eating soggy potato chips--bet you can stop at one! But if forced to penitential reading on the Feast of St. George the Jessel, guessing the categories holds off a blinding headache. ""Great idea! Filter sheets for people who smoke in bed."" (""Smoking."" Easy, huh?) ""She wants to have her hair dyed back to its original color--only she can't remember what it was."" (""Wife's appearance,"" right?) But this one is a stumper: ""One line was so long, by the time I got in to see the world of tomorrow--it was."" (""World's Fair"" by golly!) Destined to prop up ice boxes in beach cottages.
